Meanwhile, more than a dozen races across multiple states have yet to be called, including contests in Arizona and Florida for the U.S. Senate and in Georgia for governor. A Senate special election in Mississippi has gone to a runoff.

Here's the latest.

LIVE UPDATES

Wednesday, 1:42 p.m. EST -- House Minority Leader Nancy Pelosi said her fellow House Democrats succeeded in Tuesday's midterm elections because their campaigns were centered on health care. She called it a "great day for America."

"The biggest winner yesterday was health care for the American people, for our seniors and for American families," Pelosi said. "We won because from the beginning we focused on health care."

Wednesday, 1:20 p.m. EST -- Montana's Senate race is projected to be over, with incumbent Democrat Jon Tester the winner. Tester, who is projected to have won a third term by defeating Republican challenger Matt Rosendale, was one of 10 Democratic incumbents up for re-election in states that Trump won in 2016.

Democrats have won six of the seats and Republicans three. The Florida Senate race result has not been projected by ABC News.

Wednesday, 1:00 p.m. EST -- Trump at a White House news conference quarreled with some reporters and declared that his campaigning for Republican candidates in the weeks ahead of Tuesday's midterms "stopped the blue wave" of big, expected Democratic wins.

"This vigorous campaigning stopped the blue wave that they talked about. I don't know if there ever was such a thing, but there could have been if we didn't do the campaigning," the president said, noting that he held 30 rallies for Republicans over the last 60 days. "We saw candidates that I supported achieve tremendous success last night."

Wednesday, 11:37 a.m. EST -- Senate Majority Leader Mitch McConnell has warned Democrats against "presidential harassment" as they take the reins in the House of Representatives.

McConnell, a Republican from Kentucky, recalled his own party's efforts to impeach President Bill Clinton in the 1990s, saying it backfired on them.

"The whole issue of presidential harassment is interesting. I remember when we tried it in the late '90s," McConnell said. "We impeached President Clinton. His numbers went up and ours went down, and we under-performed in the next election."

House Democrats swept to power after campaigning on the promise of providing a stronger check on the Trump administration. That pledge could initiate bruising legal battles over congressional subpoenas, a stack of demands for documents and testimony from federal agencies -- including the president's tax returns -- and withering investigations into facets of Trump’s personal life, his family business and his government.

Wednesday, 10:36 a.m. EST -- Florida Democratic incumbent Sen. Bill Nelson has called for a recount in his race for re-election after unofficial results appear to show him narrowly trailing behind Republican opponent Rick Scott, who is currently the state's governor.

"We are proceeding to a recount," Nelson said in a brief statement Wednesday morning, in which he called Scott's lead "razor-thin."

A recount of all votes is mandatory in Florida if the margin of victory is less than 0.5 percentage points.

But Scott has already declared victory.

"This race is over. It's a sad way for Bill Nelson to end his career. He is desperately trying to hold on to something that no longer exists," Scott’s spokesman, Chris Hartline, said in a statement to ABC News.

Wednesday, 10:02 a.m. EST -- Republican Bob Stefanowski has conceded to Democrat Ned Lamont in Connecticut's surprisingly tight gubernatorial race.

Stefanowski made his concession during a call-in to a radio show Wednesday morning, which means Lamont will take the seat of the state's outgoing governor, Democrat Dan Malloy.

Wednesday, 9:58 a.m. EST -- Democrat Jane Mills will be the next governor of Maine.

Maine uses ranked-choice voting, in which voters list candidates in order of preference with their votes shifting to the next choice as other candidates are eliminated, which led to some concerns that the governor's race could drag out for days. But Mills captured a majority in the first round.

Wednesday, 9:48 a.m. EST –- Alaska's new governor is Republican Mike Dunleavy.

His path to victory became clearer when incumbent Independent Gov. Bill Walker dropped out of the race nearly three weeks ago. Walker threw his support behind Democratic candidate Mark Begich, but Dunleavy picked up the seat for the GOP.

Wednesday, 9:22 a.m. EST -- As Democrats prepare to take control of the House, Republicans will decide who will be their minority leader. Rep. Jim Jordan, R-Ohio, is challenging Rep. Kevin McCarthy, R-Calif., for the position.

Jordan announced his bid during an interview with The Hill on Wednesday morning, saying he plans to run for the post. An aide subsequently confirmed that to ABC News.

Wednesday, 8:45 a.m. EST -- Trump railed against House Minority Leader Nancy Pelosi for months on the campaign trail, warning his supporters of the possibility of her becoming speaker if Democrats won control of the House. But in the wake of exactly that happening in Tuesday's midterm elections, Trump took a different track, tweeting that "in all fairness," that the California Democrat "deserves" to be chosen by her fellow House members as speaker.

Wednesday, 8 a.m. EST -- Trump continued Wednesday morning to spin the midterm elections as a win for him and his party.

"Yesterday was such a very Big Win, and all under the pressure of a Nasty and Hostile Media!" Trump wrote in a series of tweets Wednesday morning. "To any of the pundits or talking heads that do not give us proper credit for this great Midterm Election, just remember two words - FAKE NEWS!"

Wednesday, 5:23 a.m. EST -- The Kremlin offered its two cents (or rubles) on the midterm results, saying that even with the change in Congress, it was hard to see how relations between Russia and the U.S. could get worse.

"It’s possible to suggest with a high degree of confidence, that of course there is no rosy outlook for normalizing Russian-American relations on the horizon. That does not mean that we will not seek dialogue, we want dialogue,” Kremlin spokesman Dmitry Peskov said in a daily briefing call Wednesday.

Wednesday, 2:23 a.m. EST -- Democrat Joe Cunningham has defeated Republican Katie Arrington in South Carolina’s 1st Congressional District.

Wednesday 2:18 a.m. EST -- Republican Yvette Herrell has defeated Democrat Xochitl Torres Small in New Mexico’s 2nd Congressional District, ABC News can project. Herrell is the first woman to represent the district.

Wednesday 1:48 a.m. EST -- Democrat Lauren Underwood will become the first black woman to represent her district, in Illinois’ predominately white 14th Congressional District, ABC News can project based off of exit polls.

Wednesday 1:37 a.m. EST -- Twenty-one congressional districts voted for President Barack Obama and then for President Trump. The GOP was able to hold down 12 of them in Congress. ABC News can project that Democrats will flip six of those seats.

Wednesday 1:30 a.m. EST -- In Georgia, a vote count error in the state has narrowed the lead of Republican candidate Brian Kemp over Democratic candidate Stacey Abrams. Kemp is just above the 50 percent threshold. If his share of the vote falls below 50 percent, Georgia law states that the race would go to a runoff.

The Abrams campaign said that they don't expect to concede tonight, and that they believe there are enough votes still outstanding to force a runoff.

"We are going to make sure every single vote is counted," Abrams said.

Wednesday, 1:25 a.m. EST -- Democrat Lizzie Pannill Fletcher has defeated GOP Rep. John Culberson in Texas’ 7th Congressional District, which includes the Houston suburbs, ABC News can project.

Wednesday, 1:00 a.m. EST -- In Maine, another governorship will likely flip in favor of Democrats at the gubernatorial level. Republican candidate Shawn Moody has conceded to Democratic candidate Janet Mills. ABC News has not yet projected a winner in the race.

Wednesday, 12:49 a.m. EST -- The Democrats will pick up between 32 and 36 seats in the House, ABC News can project.

Wednesday, 12:41 a.m. EST -- Republican Rep. Steve King has won re-election to Iowa’s 4th Congressional District, fending off Democratic challenger J.D. Scholten, ABC News can project.

Wednesday, 12:38 a.m. EST -- The crowd at the Democratic Election Night party in Phoenix was at first buoyed by hope and lively music, but started to thin out as it seems more and more likely that Arizona's U.S. Senate race might be too close to call tonight.

The race between Democrat Rep. Kyrsten Sinema and Republican Rep. Martha McSally to fill Sen. Jeff Flake's seat is neck-and-neck.

Sinema supporter Michelle Rose predicted they'd have a winner by 11 p.m. MST (1 a.m. EST), and Timothy Bradley said he thought it'd be either by 11 p.m. or 12 a.m. Ginny Doherty left a little more wiggle room, telling ABC News she thought it would be closer to 2 a.m. MST.

According to officials, those guesses could be way off.

Part of the problem is that there are still hundreds of thousands of votes that still need to be tabulated in the state's most populous county, Maricopa County, which includes Phoenix. Maricopa County Recorder Adrian Fontes told ABC News tonight that it could take up to a week or more for Maricopa to have their final results.

Republican Senate candidate Rep. Martha McSally greets voters in a holding room outside of her election night party in Phoenix, Nov. 6, 2018.

Sinema and McSally are battling it out for the seat that's being left open by Sen. Jeff Flake's decision not to seek re-election.

Preliminary exit poll results suggest that Sinema is getting help by moderate Arizonans, with a 27 point margin that has her up 63 percent to McSally's 36 percent.

That appeal, and her perceived independent streak, is what drew Matt Winter to volunteer for Sinema.

"In recent history we’ve had John McCain and Jeff Flake and Republicans who have a strong independent streak, and she’s a Democrat with a strong independent streak," Winter told ABC News.

Wednesday, 12:18 a.m. EST -- Whatever the results in any given election, the rise in diversity is nothing short of remarkable.

In the 1990 midterm elections, the division of whites and nonwhite voters was 91-9 percent. Today it’s 72-28 percent. The most non whites voters ever in a midterm, and a scant 1 point shy of the record for any election in 2016. The Hispanic vote came in at 11 percent, again a new midterm high, and matched its all-time high from 2016.

Wednesday, 12:15 a.m. EST -- Democrat Antonio Delgado will defeat incumbent GOP Rep. John Faso in New York’s 19th Congressional District, ABC News can project based off of an analysis of polling data.

There are currently two Native American representatives in the House — both men from Oklahoma.

"We knew we were in a tough campaign. We knew we took some votes that people were critical of," Heitkamp said, an apparent reference to her vote against Justice Brett Kavanaugh’s confirmation to the Supreme Court.

But Heitkamp said she never intended to "to rubber stamp any one party."

Trump held rallies in West Virginia a whopping five times in an effort to turn a state he won by 42 points red all the way.

Tuesday, 11:28 p.m. EST -- Although ABC News can project the U.S. Senate race in North Dakota for Republican Kevin Cramer, Democratic incumbent Sen. Heidi Heitkamp hasn’t conceded just yet.

Tuesday, 4:34 p.m. EST -- Dozens of young Native Americans marched to their local polling place on a reservation near Belcourt, North Dakota.

The group of young men and women, members of the Turtle Mountain Band of Chippewa, carried signs that read, "Don’t disenfranchise us," as they chanted in unison, "North Dakota, you can’t do that!"

By the time they reached the polls, more than a thousand people had already cast ballots hours before the polls were to close. In comparison, just 950 people voted at the same polling site in 2016, according to an election official there.

Tribal leaders have scrambled to print at least 3,500 new tribal IDs for Native Americans on reservations in North Dakota in response to the state’s new voter ID law, which requires North Dakotans to provide a state or tribal ID with a residential address in order to vote. Many Native Americans living in rural communities on or near reservations don’t have residential addresses.

Tuesday, 4:21 p.m. EST -- The issues with electronic poll books in Indiana's Johnson County have been "resolved," election officials said.

The midsize county, which is located south of Indianapolis, will not be extending voting hours but officials will add more voting machines if need be, according to Johnson County election board chairman Phil Barrow.

Election Systems & Software, the electronic voting vendor the county employs, also confirmed in a statement that the issues were fixed.

We apologize to voters and to elections officials in Johnson County, Indiana for longer wait times than expected, and we thank everyone for their patience."

Johnson County is in a congressional district considered safe for Republicans, but the Senate race in Indiana is considered competitive, with Democratic incumbent Joe Donnelly trying to beat back a challenge by Republican Mike Braun.
