Sanders projected to eke out narrow win in New Hampshire primary, with Buttigieg, Klobuchar close on his heels

MANCHESTER, N.H. -- With 97% of the expected vote reported, Vermont Sen. Bernie Sanders was the top performer in New Hampshire's Democratic primary, followed by former Indiana Mayor Pete Buttigieg and Minnesota Sen. Amy Klobuchar.

The first-in-the-nation primary heated up on Tuesday as the first decisive outcome this cycle after the tumultuous Iowa caucuses.

The candidates made their final pleas to voters across the state to outline their vision for the country, rebuke President Donald Trump, call for party unity and made more overt contrasts with their rivals.

While Sanders and Buttigieg battled it out for the top spots in the primary, Massachusetts Sen. Elizabeth Warren and former Vice President Joe Biden jockeyed for positions, as both have found themselves in a tight race for third and fourth place in recent polling.

Here's how the day unfolded.

11:48 pm South Carolina and Nevada could produce new front-runners, analysts say

Moving forward, primaries in Nevada and South Carolina could produce more competition as former Vice President Joe Biden and billionaires Michael Bloomberg and Tom Steyer look to gain delegates in the next two primaries.

Tuesday night, Biden traveled to South Carolina, a state he has focused much of his attention on in recent weeks. ABC News Correspondent Eva Pilgrim noted that Biden event attracted the most “diverse” crowd she’s seen at a campaign event for the former vice president. While Pilgrim said that South Carolina is “not do or die” for his campaign, it is definitely “important.”

South Carolina will also be important for Bloomberg. ABC News Contributor Heidi Heitkamp. a former North Dakota senator, said that “the winner tonight is Michael Bloomberg” because “no one has emerged as the presumptive candidate.” Heitkamp believes that moving forward Bloomberg could fully cement himself within the race with strong performances in both South Carolina and Nevada.

Continuing the conversation, former campaign manager for New Jersey Sen. Cory Booker's presidential bid Addisu Demissie added that “Tom Steyer has been quietly working in South Carolina and Nevada.” Demissie continued to push that Steyer could gain some momentum heading into Super Tuesday if his work in the two states pays off.

Vermont Sen. Bernie Sanders, the projected winner of the New Hampshire primary, addressed a cheering crowd in New Hampshire on Tuesday night and proudly touted his diverse support in building a coalition aimed at taking progressive approaches to health care, resolving student debt and curbing climate change to the White House.

11:02 p.m. Buttigieg thanks diverse group of voters for his strong finish in New Hampshire

Pete Buttigieg appeared triumphant as he stood before his New Hampshire supporters Tuesday night as he trailed in second place closely behind Vermont Sen. Bernie Sanders in the Democratic primary.

"So many of you turned out -- die-hard democrats, independents unwilling to stay on the sidelines and even some former Republicans willing to try something new," he said. "So many of you chose to meet a new era of challenge with a new generation of leadership."

Buttigieg congratulated his competitors, especially Sanders on his win, adding that he has admired the Vermont senator since he was a high school student.

"Vote blue, no matter who," Buttigieg said to the crowd. "We are on the same team."

11 p.m. How did Hispanics vote?

New Hampshire has come under fire for its early status among concerns about lack of diversity in voting before Super Tuesday. Only 2% of its population is Hispanic or Latino, but of that 2%, 40% voted with Sanders, according to ABC News analysis of exit poll data.

All other candidates had Hispanic support in the teens or lower, including Biden who finished the night with 10%.

According to ABC News Polling Director Gary Langer, there were 110 Hispanics tallied in exit polls, just enough for analysis. )There were only 62 African Americans in this count, not enough for analysis).

ABC News' Polling Director Gary Langer reported.

10:48 p.m. Where do the suburbs stand?

With 82% of expected vote reporting, as of 10:46 p.m. ET, Bernie Sanders is currently leading with 26%, followed by former South Bend, Indiana Mayor Pete Buttigieg, with 24% and Minnesota Sen. Amy Klobuchar, with 20%.

The gap between Buttigieg and Vermont Sen. Bernie Sanders is still very close, with only 4,311 votes separating them at this point.

Massachusetts Sen. Elizabeth Warren and former Vice President Joe Biden are still vying for fourth and fifth with Warren having 9% and Biden holding only 8%. About 2,200 votes separate the two.

Some of the state's key suburbs are still outstanding with 0% of the vote in, including Hooksett, Goffstown, Dunbarton, outside of Manchester, a city in which Sanders delivered a strong performance.

Around Concord, Buttigieg appears to be leading across those suburbs, particularly in Loudon and Bow, where he is the top vote-getter. But another suburb of Concord, Pembroke, has 0% of precincts reporting. In one exurb of Concord, Allenstown, Sanders topped Buttigieg with 100% of precincts reporting, 27%-22%. Around Nashua, Litchfield remains at 0%, and in another suburb, Amherst, Buttigieg clinched 29% of the vote, compared to Klobuchar's 26%, with 100% of precincts reporting there.

Hanover, home to Dartmouth University, was supposed to one of the foundations of Sanders' youthful base, but it sided with Buttigieg with 26% of the vote to Sanders' 20%.

ABC News' Kendall Karson and Quinn Scanlan reported.

10:40 p.m. Buttigieg nips at Bernie's heels after Iowa caucus debacle

After the problem-plagued Iowa caucuses and former South Bend, Indiana Mayor Pete Buttigieg's surprise catapult to the presumed top-tier, he has remained on Vermont Sen. Bernie Sanders' heels in the days leading up to New Hampshire.

Statewide polling showed him consistently in second place since the Iowa caucuses, only points behind Sanders and within the margin of error, bumping former Vice President Joe Biden for the second place position in a number of polls.

A New Hampshire poll released on Jan. 23 showed Buttigieg at 15%, nearly tied with Biden, in third place trailing behind Sanders.

Polls released after Buttigieg's impressive results in Iowa showed him skyrocketing to second place and maintaining a hold at or around 20%.

A poll released on Sunday evening showed Buttigieg at 22% with Sanders at 29%.

Buttigieg spent 30 days in New Hampshire and held at least 80 events.

His apparent strong showing in the primaries captured the attention of President Trump on Tuesday night.

Trump blasted the former South Bend, Ind. mayor on Twitter, saying he was "giving crazy Bernie a run for his money."

"Bootedgeedge (Buttigieg) is doing pretty well tonight. Giving Crazy Bernie a run for his money. Very interesting!" he tweeted.

10:18 p.m. Klobuchar a 'big surprise' in New Hampshire, says ABC News political analyst.

Minnesota Sen. Amy Klobuchar's success in New Hampshire at 20% of the vote is a "big surprise," considering polls had her pulling in juts 6% of the vote just a few days ago, said ABC News Chief Political Analyst Matt Dowd.

Dowd described New Hampshire as a "hugely disappointing night" for Joe Biden and Elizabeth Warren, especially considering that their numbers combined, at 8% and 9% consecutively, do not add up to Klobuchar's numbers.

While Klobuchar did well, what remains to be seen is whether she can have a "second act," Dowd said, adding that she will now have a "target on her back" and reminding the public that Bill Clinton only won one of the first 11 primaries and caucuses in 1992.

"She will be tested in the next two or three weeks, unlike anything she's ever been tested before," Dowd said.

10:12 p.m. Strong liberals lift Sanders, Buttigieg keeps a broad base as New Hampshire centrists bring Klobuchar into contention

According to a final analysis of New Hampshire exit polls, older and more educated voters, moderates and those looking for a candidate to unite the country lifted Minnesota Sen. Amy Klobuchar to competitive status in the New Hampshire Democratic primary, largely at former Vice President Joe Biden’s expense. Vermont Bernie Sanders held on to younger and very liberal voters, and, as in the Iowa caucuses last week, former South Bend, Indiana Mayor Pete Buttigieg demonstrated appeal across a range of groups.

ABC News' Polling Unit Director Gary Langer reported.

10:07 p.m. Where did Warren stack up with her competitors on her ground game?

Warren had the most visits to the state out of her competitors, coming in at 28 over the primary cycle, but held far fewer events than some of her competitors.

Andrew Yang, who ended his presidential bid on Tuesday night, held 134 events in the Granite State, the most of any of the Democrats, followed by Hawaii Rep. Tulsi Gabbard at 114, Colorado Sen. Michael Bennet, who also left the race Tuesday night, held 103. Warren held at least 62 and overall, spent 40 days in the state.

Based on preliminary exit polls, Warren clinched support from 10% of women, while Klobuchar secured the most support from women at 25%.

53% of voters, based on preliminary exit polls, between the ages of 18-35 have opted for Sanders, followed by Buttigieg at 18%. Warren fared the best among voters aged 30-44 at 13%.

ABC News' Christopher Donato reported.

10 p.m. Trump targets Steyer, Warren after poor showings in New Hampshire.

President Donald Trump took to Twitter to target the Democratic candidates that did not fair well in the New Hampshire primary.

Trump also criticized Massachusetts Sen. Elizabeth Warren for "having a really bad night" in New Hampshire, accusing her of "sending signals that she wants out."

9:55 p.m. Klobuchar vows to unite the country to defeat Trump

As the results for the New Hampshire Democratic primary come in, Minnesota Sen. Amy Klobuchar addressed her supporters on the heels of an apparent third-place finish in the state, vowing to unite the country in an effort to defeat Trump, who she called the "great divider."

"We see that what unites us is so much deeper than what divides us," she said. "We know that the heart of America is so much bigger than the heart of this guy in the White House."

Klobuchar emphasized that the race "is not about the loudest voice or the biggest bank account" but rather "the best ideas and the person who can turn those ideas into action."

"We know that we can win by bringing people with us instead of shutting them out," she said.

Klobuchar and her team are "taking this message of unity to the country" as they look ahead to Nevada and South Carolina, she said.

Among those towns with yet to report, some of the biggest towns are Derry, Hanover and Durham - the last two of which are home to some of the state's big universities - Dartmouth and University of New Hampshire. These areas are considered epicenters of Sanders' core base.

According to a preliminary analysis of exit polls, Sanders is performing best among men, voters making under $50,000 and voters with no college degree. Women are narrowly backing Buttigieg, and those with a college degree are siding with Klobuchar.

I love the idea of democracy, and I want to make sure that our generation passes this democracy intact at least, if not in better shape, to the next generation of Americans. And tonight as we stand here, we can’t say that we’re in very good shape. Our democracy is at risk. The ability for people to work hard and live a middle class life in this country is at risk."

We still have 98% of our delegates for our nomination up for grabs. And Americans in every part of the country are gonna make their voices heard," she told supporters.

She's also turned her focus on "unwinnable fights" in recent days, saying she's "been winning unwinnable fights pretty much all my life -- we persist and we win," Warren said in Manchester on Saturday night.

8:17 p.m. Klobuchar looks ahead of New Hampshire.

Minnesota Sen. Amy Klobuchar released two ads in Nevada before the results in New Hampshire were even finalized.

The ads are set to air in the Las Vegas and Reno markets Wednesday and highlight issues critical to both liberal and moderate democrats, such as healthcare, prescription drugs and the economy.

ABC News' Lissette Rodriguez reported.

8:12 p.m. Klobuchar leads with women, based on preliminary exit poll results.

There’s a substantial gender gap in the New Hampshire results; Sanders does 9 points better with men than women; Klobuchar, 9 points better with women than men. Buttigieg, true to form, ran about evenly in both groups.

Klobuchar prevailed among college-educated women – winning 32 percent, followed by 22 percent for Buttigieg, 19 percent for Sanders and just 13 percent for Warren. Non-college men backed Sanders with 35 percent; Buttigieg came distantly second in this group.

As noted, Sanders, for all his strengths, has a “too liberal” problem – 52 percent of New Hampshire voters described him this way in preliminary exit poll results. They went for Klobuchar (39 percent) and Buttigieg (29 percent), with just 12 percent backing Biden.

Biden also had trouble among the few nonwhites in the electorate, a group whose support he’s been banking on. Sanders won 27 percent of this group, Biden 21 percent, with Buttigieg and Klobuchar trailing at 13 percent apiece. One reason is that nonwhites were somewhat younger than the whites who turned out, and, as noted, young voters favored Sanders.

Health care was the top-cited issue among four that were tested, and Sanders won those who picked it. He also won voters focused on income inequality. Those who care most on climate change and foreign policy tilted toward Buttigieg. Klobuchar won similar levels of support across these issue groups.

ABC News' Polling Unit Director Gary Langer reported.

8:00 p.m.Older voters, moderates and those looking for a candidate to unite the county: ABC News analysis

Based on preliminary analysis of New Hampshire primary exit polls, older voters, moderates and those looking for a candidate to unite the county aided Amy Klobuchar in the New Hampshire Democratic primary, all at Joe Biden’s expense. Bernie Sanders held on to younger and strongly liberal voters, and, as in the Iowa caucuses last week, Pete Buttigieg demonstrated appeal across a range of groups in preliminary exit poll results.

Whatever divided these voters, they were united in one regard: a remarkable 81 percent described themselves as “angry” about the Trump administration.

Backing someone who can unite the country was one of the top two attributes of concern, and Klobuchar won 31 percent support in that group, essentially even with Buttigieg, at 29 percent. Preliminary results also found Klobuchar prevailing among seniors and running well – again with Buttigieg – among moderates.

Klobuchar, 59, and Buttigieg, 38, also benefitted from their comparative youth. With Sanders, Biden and Elizabeth Warren in their 70s, two in 10 voters said candidate age was an important factor in their vote, and six in 10 of them backed Klobuchar or Buttigieg. Further, Klobuchar won 30 percent of those who called the most recent ABC News debate important in their decision, and she and Buttigieg roughly split those who made their choice in the campaign’s closing days.

Sanders, for his part, produced another strong performance among younger voters – not just under 30, but up to age 44 – and those who called themselves very liberal. He ran well but did not dominate among “somewhat” liberals, and fell back among moderates.

In contrast with Klobuchar, Sanders won voters seeking a candidate who can “bring needed change” as well as those looking chiefly for one who “cares about people like me.” Among his best groups were the nearly six in 10 voters who back a government run, single-payer health care system. His support among those voters was triple that of Elizabeth Warren, another champion of a single-payer approach.

Sanders also won handily, with 37 percent, among those chiefly seeking a nominee who “agrees with you on major issues.” But many more voters were focused instead on the candidate who can beat Donald Trump, and there Sanders’ support fell by half.

A similar result came in a question asking whether the next president should return to Barack Obama’s policies or pursue a more liberal approach. Voters divided about evenly – with Sanders soaring among those looking for more liberal policies, but cratering among those favoring for a return to the Obama era.

Buttigieg collected votes across an array of groups, much the same as in his top-two finish in the Iowa caucuses last week. Preliminary results found him running a distant second to Sanders among 18- to 29-year-olds (a poor group for Klobuchar), yet also second to Klobuchar among seniors (a poor group for Sanders). Buttigieg also did notably well with better-off voters, winning about three in 10 of those with household incomes of $100,000 or more.

7:37 p.m. ABC News exclusive: Don Jr blasts Buttigieg

AMHERST, N.H.—A confident Donald Trump Jr told ABC News in an exclusive interview that he believes his father, President Donald Trump, will be the big winner tonight "much like Iowa," and called former South Bend, Indiana Mayor Pete Buttigieg "the NASCAR driver of the Democrat party sponsored by every billion you can imagine."

"I think much like Iowa, Donald Trump is going to win tonight. That's the one thing I can pretty much assure everyone of. It's been incredible to go around the state again, to be back here now vs 2016, we have a team, we have people, we have enthusiastic people who have seen the president deliver the things that he was promising back then. So it's the difference between maybe he could do it and hey, he's actually done it. The energy has been totally through the roof. It's been awesome."

ABC News' Will Steakin reported.

7:02 p.m. Pete Buttigieg responds to Michael Bloomberg "You don’t xerox people.”

In an exclusive interview with ABC News Chief White House Correspondent Jonathan Karl, former South Bend, Indiana Mayor Pete Buttigieg responded to new reports about Michael Bloomberg's controversial stop-and-frisk policy, saying "It’s problematic." “There’s certainly tremendous racial bias in the way that stop and frisk has played out. And I’m not gonna -- I’ll leave it to others to characterize Mayor Bloomberg."

"Any law enforcement strategy that seems to regard people as profile rather than as human beings, especially seeing how this has disproportionately impacted black and brown Americans is something that just has no place in an equitable future," he said. "You don’t xerox people. And it’s upsetting to hear that kind of language.”

7 p.m. Meet the voters who cast the 1st NH primary ballots of 2020

North Country is a stretch of rural New Hampshire without government services -- there's no trash pickup, and residents dig their own wells -- and the nearest hospital at which to see a specialist could be hours away.

Voting booths here have been barns and laundry rooms and bedrooms and even dining rooms.

They opened at midnight on Tuesday. Read more about the community here.

6:31 p.m. ABC News partner FiveThirtyEight is up with their live blog

ABC News partner FiveThirtyEight is up with their live analysis blog.

Welcome to New Hampshire primary night!! Hopefully, we’ll actually get results tonight in a timely fashion (looking at you, Iowa).

A crew of FiveThirtyEighters has been here on the ground in New Hampshire since the debate on Friday, and we’ve been busy covering candidate events and hitting the campaign trail (and maybe a tattoo parlor) ever since.

Our primary forecast is frozen. We won't update it with any new data, including polls, until all the results from New Hampshire are it. In New Hampshire, our forecast suggests Sanders is likely to win the most votes, with a 2 in 3 shot. Buttigieg has about a 3 in 10 chance of winning the most votes. The likelihood for the other 2020 candidates to finish first tonight is low.

Check out Nate Silver’s piece on 28 scenarios for how things could shake out in New Hampshire and beyond — but remember that whoever finishes in second or third place could capture a lot of media attention, too, depending on the margin. For instance, a strong second-place finish by Buttigieg could keep him viable, and a second-place finish by Warren or Klobuchar could jumpstart either one of their campaigns.

6 p.m. Democratic voters making last-minute decisions.

About 48% of Democratic primary voters said they made up their minds about their chosen candidate either on Tuesday or within the last few days, with 16% deciding today, according to preliminary results from the New Hampshire primary exit poll.

About 59% of Democratic primary voters said they don't think Trump's impeachment made a difference in his chance of being re-elected, and about 64% of Republican primary voters said they think it helped his chances.

Turnout among conservatives is at a record-high in the GOP primary, with about 81% labeling themselves as conservatives, up from the previous record of 71% in 2016. About 61% of voters in the Democratic contests are liberals, according to the preliminary exit polls.

About 83% of GOP voters say they support building a wall "along the entire U.S. border with Mexico," and about 88% say Trump has mostly kept his campaign promises.

5:15 p.m. Turnout among independents and liberals is running high.

Turnout among these two groups may hold the key to the Democratic primary, according to preliminary results from the New Hampshire primary exit poll.

About 45% of voters in the early results are independents, compared to 40% in 2016, when independents boosted Sanders to an overwhelming victory in New Hampshire, winning 73% of their votes versus Hillary Clinton.

On the issues, about 58% of voters said they support a single government health plan for all Americans, matching to about 57% in the Iowa caucuses, and about 37% called health care the most important issue for their vote, according to the preliminary results from the exit polls.

5:15 p.m. Here's the state of play in New Hampshire so far.

Under pressure to excel in the Granite State amid a fiercely competitive race, many candidates have camped out in the state since early last week, spending much time openly criticizing their rivals' records and experience.

Only eight days after the contest in Iowa -- caucuses which were thrown into turmoil due to "inconsistencies" in reporting results -- two front-runners have emerged.

The state Democratic Party ultimately projected former South Bend, Indiana, mayor Pete Buttigieg the winner of the caucuses Sunday night, awarding him two more delegates than his closest competitor, Vermont Sen. Bernie Sanders - setting up a bitter fight between the two in New Hampshire.

While Buttigieg and Sanders battle it out for the top spot in the primary, Massachusetts Sen. Elizabeth Warren and former Vice President Joe Biden are jockeying for a last-minute boost, as both have found themselves in a tight race for third and fourth place in recent polling.

Though Biden has seemingly already admitted defeat in New Hampshire -- announcing plans to skip out early and head to South Carolina ahead of the Feb. 29 primary.

But New Hampshire is also crowded by eleventh-hour momentum from Minnesota Sen. Amy Klobuchar, as well as a slate of lower-tier contenders vying to drain some support from the top two tiers, including Colorado Sen. Michael Bennet, Hawaii Rep. Tulsi Gabbard, former Massachusetts Gov. Deval Patrick and entrepreneur Andrew Yang.
