ABC News now projects that Democratic Rep. Adam Schiff and Republican Steve Garvey, a former Major League Baseball player, will advance in California's U.S. Senate race. This will set up a traditional Democrat-versus-Republican contest in November, which is unlikely to be interesting in deep-blue California. With 41 percent of the estimated vote reporting, Schiff leads Garvey 37 percent to 29 percent. That suggests that Schiff's spending on ads to improve Garvey's name recognition among Republicans succeeded, allowing the congressman to avoid facing fellow Democratic Rep. Katie Porter, who is in third with 15 percent. And while we are still waiting for more returns, our map of the top-two Senate primary shows only Schiff and Garvey holding leads in any county that has results, speaking to their edge.

With all precincts reporting in North Carolina’s 8th congressional district, Baptist minister Mark Harris is winning 30.44 percent of the vote per North Carolina's State Board of Elections, successfully avoiding a runoff and securing his spot on the ballot in the solidly Republican district after ballot fraud allegations kept him out of Congress in 2018.

I've been keeping half an eye on the race for the chief justice for the state Supreme Court in Arkansas, and the four-way race is very close. With almost all of the expected vote in, two sitting justices, Justice Rhonda Wood and Justice Karen Baker, are virtually tied at about 27 percent each, according to The New York Times. If they remain the top two candidates when all the votes are in, they'll had to a runoff in November. Fun fact: Baker is from my hometown of Clinton, Arkansas.

A big question is whether Trump is line to mathematically clinch the nomination next Tuesday, March 12 — the earliest possible date on the calendar that a candidate (namely, Trump) could claim a majority of the GOP's 2,429 national delegates. And it looks like it could be close.

Trump entered the night with 247 delegates to Haley's 43, according to 538's delegate benchmark tracker, and he looks in line to win roughly 775 to 805 delegates out of 854 that were up for grabs today. That would put him at around 1,025 to 1,055 delegates. If he's on the short end of that range, a Trump sweep of all delegates in contests after today up through March 12 would put him just above the 1,215 mark to clinch. This makes the Vermont result, where Haley is just above 50 percent, pretty important, because it would mean the difference between Trump claiming about 0 delegates, or claiming 8 should Haley fall short of a majority in her victory.

Haley took the stage in a bright red dress and in front of a row of American flags just after 10 a.m. from South Carolina, and announced she was suspending her presidential campaign. She began with a retrospective of the start of her campaign, and reiterated her conservative principles, including a low national debt, a small federal government and the need to promote democracy worldwide by standing by America's allies. With that, the final Trump challenger is out of the race, and Trump is the presumptive nominee, a fact Haley acknowledged.

Like most major candidates who ran for the Republican nomination, other than Trump, Haley had previously signed the RNC's pledge to support the eventual nominee, but she's distanced herself from that pledge a bit recently. Haley didn't endorse Trump this morning, but she did congratulate him, while slightly criticizing the way that he's run his campaign. "We must turn away from the darkness of hatred and division," she said. She went on to say that Trump needed to bring people into his cause, saying, "It is now up to Donald Trump to earn the vote of those in our party and beyond it." Haley has noted in previous speeches that she's captured a sizable portion of the vote in some states, even winning Washington, D.C., and Vermont, signaling that some Republican voters are dissatisfied with the former president as a choice for the future.

In the end, as Meredith noted, she made a somewhat rare reference to the historic nature of her campaign. She's the first Republican woman win any state's nominating contest, and she noted that her mother, a first-generation immigrant, had gotten to vote for her for president in South Carolina. She directed her final lines, quoting from the Book of Joshua, to women and girls who had watched her campaign.
