Super Tuesday primaries 2024: Trump and Biden dominate, Haley drops out

March 5 was Super Tuesday — the biggest election day of the year until the one in November! With former President Donald Trump projected to win 14 of the day's 15 GOP presidential nominating contests, former U.N. Ambassador Nikki Haley announced Wednesday morning that she is suspending her campaign.

It was also the first downballot primary day of 2024, with important contests for Senate, House and governor in states like Alabama, California, North Carolina and Texas.

538 reporters, analysts and contributors broke down the election results as they came in with live updates, analysis and commentary. Read our full live blog below.

The field is set in California's 47th and 49th


ABC News is also projecting the general-election candidates in two California House races:

- In the 47th District, Republican Scott Baugh and Democrat Dave Min have advanced out of the top two primary, leaving Democrat Joanna Weiss out in the cold. This is the seat that Democratic Rep. Katie Porter vacated to run for Senate, and it will be tough for Democrats to defend. Some Democrats are worried that Min's DUI arrest last year could drag him down.

- In the 49th District, Democratic Rep. Mike Levin and Republican Matt Gunderson have advanced to the general election. Biden carried this district by 11 points in 2020, so it'll probably stay in Democratic hands, but it's not out of the question that Gunderson could win in the fall.

More runoffs projected in Texas, North Carolina


Catching up on some ABC News race projections that we missed earlier:

- In the Republican primary for North Carolina's 13th District, ABC News projects that Kelly Daughtry and Brad Knott will advance to a May 14 runoff. This is currently a Democratic-held seat, but the GOP legislature redrew it to be safely Republican, so whoever wins the runoff should be a shoo-in in November.

- In the Republican primary for Texas's 12th District, ABC News projects that Craig Goldman and John O'Shea will advance to a May 28 runoff. This is a solidly red open seat currently represented by retiring Rep. Kay Granger.

- And a bit of a surprise in the Republican primary for Texas's 23rd District: incumbent Rep. Tony Gonzales garnered just 45 percent of the vote, forcing him into a runoff with second-place finisher Brandon Herrera. Gonzales was censured by the Texas GOP last year for supporting bipartisan gun legislation in the wake of the shooting in Uvalde, which is in his district. Clearly, the GOP base is still not happy with him.

Several incumbents ousted in the Texas state House

As we explained yesterday, Texas Gov. Greg Abbott, Texas Attorney General Ken Paxton and Trump all set out to defeat several incumbent Republicans in the Texas state House yesterday (albeit for different reasons). The Associated Press has now projected winners in most of those races, and here's how they turned out: In total, at least eight Republican incumbents lost their primaries after being targeted by one of those three men. Another seven, including Speaker Dade Phelan, were forced into runoffs.

Abbott's muscle looks like it was the most effective: Five of the 10 incumbents he targeted (over their opposition to his school-voucher plan) lost, and another three went to runoffs. Trump also did OK: Two of the eight incumbents he targeted lost, and three more went to runoffs. Paxton didn't have as high of a success rate: Only seven of the 35 incumbents he targeted lost, although seven more were forced into runoffs. That's maybe not too surprising, though, since unlike Abbott, Paxton didn't put a ton of money where his mouth was.

Dean Phillips suspends his campaign, endorses Biden


Minnesota Rep. Dean Phillips ended his campaign for president today and endorsed Biden's reelection campaign. Phillips got into the race last fall, citing Democratic worries about Biden's age and ability to beat Trump. But his campaign never took off, even in New Hampshire, where he focused much of his efforts because Biden wasn't on the ballot due to the state's primary having violated the national Democrats' new calendar rules. Phillips won 20 percent of the New Hampshire vote, but he didn't clear 10 percent in any other state where he got on the ballot. Yesterday, he earned 8 percent in his home state of Minnesota and 9 percent in Oklahoma, his best showings otherwise.

Although some Democrats share Phillips's concerns about Biden, Phillips predictably struggled because the incumbent president remains relatively well-liked by those in his party. Phillips was an unusual primary challenger in that he didn't have sizable ideological disagreements with Biden that stoked his run — the moderate congressman was not from the Bernie Sanders wing of the party, for instance. And Phillips's overall performance reflects the lack of appetite for a center-left alternative to Biden — who hails from that part of the party — or at least one who didn't already have a sizable standing. Rather, the intraparty dissatisfaction with Biden has been felt more on the left, which has been especially critical of Biden's handling of the Israel-Gaza situation. (See: the "Uncommitted" protest movement getting more votes than Phillips in his home state.) Tellingly, Marianne Williamson's minor left-wing campaign has actually won more votes than Phillips in 10 of the 15 primaries they both participated in.

All incumbent Republicans lose in the Texas Court of Criminal Appeals primaries


As Nathaniel mentioned yesterday, in 2022, eight Republican judges on the Texas Court of Criminal Appeals ruled that the attorney general cannot prosecute election-related cases without the participation or permission of a local prosecutor, a decision that upset Attorney General Paxton, Trump, and Gov. Abbott. Last night, three of those incumbents were up for reelection, and all three faced primary challengers endorsed by Paxton, Trump and Abbott. According to the Associated Press, with over 95 percent of the expected vote reported, all three appear to have lost to their primary challengers: Presiding Judge Sharon Keller is losing 37 percent to 63 percent to appellate lawyer David Schenck, Judge Barbara Parker Hervey is losing 34 to 66 percent to former Assistant District Attorney and businesswoman Gina Parker, and Judge Michelle Slaughter is losing 46 to 54 percent to criminal lawyer Lee Finley.

Harrigan wins in North Carolina's 10th


Overnight last night, ABC News projected that firearms manufacturer Pat Harrigan will be the GOP nominee in North Carolina's 10th District. He defeated more conservative Republican Grey Mills 41 percent to 39 percent. The 10th District is a solidly red seat currently represented by retiring Rep. Patrick McHenry, and Harrigan should have no trouble winning it in the fall.

The uncommitted campaign against Biden expands


Last night, the "uncommitted" campaign made headway in a few more states. After a protest vote for Biden's response to Israel's war against Gaza helped net over 100,000 uncommitted votes in last week's Michigan Democratic primary, supporters of the Listen to Michigan campaign expanded their efforts to other states with "uncommitted" or similar language as an option on primary ballots.

With 89 percent of the expected vote reporting, 19 percent of Democratic primary voters in Minnesota voted uncommitted, eclipsing the 13 percent reached last week in Michigan. That means "uncommitted" will send at least 8 (and up to 11) delegates from Minnesota to the Democratic National Convention in August, per the latest ABC News projections.

"No preference" also garnered 13 percent of ballots cast in North Carolina and 9 percent in Massachusetts, while 8 percent of primary voters in Colorado chose "noncommitted." However, those aren't enough to meet their respective states' thresholds to send a delegate to the national convention. (That's 15 percent in all three of those states.)

The first big endorsement of the general election?

While Haley called on Trump to earn Republicans' votes, Mitch McConnell suggested that he already has. "It is abundantly clear that former President Trump has earned the requisite support of Republican voters to be our nominee for President of the United States," McConnell said in a statement. The rest was pretty standard endorsement fare, going on to tout Trump's accomplishments on tax reform and judicial appointments, and criticizing Biden.

It's an undramatic end to the minor drama over whether the soon-departing majority leader would endorse Trump, with whom he's undoubtedly had a rocky relationship. In the end, McConnell waited until just after Trump's final major opponent dropped out to fall in line. With one of the last major (potential) party holdouts in his corner, the general election train is in full swing for Trump.

The new delegate math


According to the latest numbers from our colleagues at ABC News, Trump has 1,051 of the 1,215 delegates he needs to mathematically clinch the Republican nomination for president. Haley's withdrawal from the race puts him on track to reach that magic number next Tuesday, March 12. A total of 199 delegates will be allocated between now and then, and presumably Trump will win all or almost all of them.

Haley calls on Trump to 'earn' Republicans' votes


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 second Republican woman to win delegates in a presidential nominating contest and first to 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.
