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

538 tracked how Trump and Haley did, plus key U.S. House and Senate races.

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.

Utah Democrats decide

ABC News projects that Biden will win the Utah Democratic primary. With about 47 percent of the expected vote counted, Biden has 88 percent in the Beehive State.

Moore leads Carl in all-incumbent clash in Alabama's 1st District

Time for our first update of what's happening in the Republican primary in Alabama's 1st District. There, court-ordered redistricting precipitated an incumbent-versus-incumbent contest between Reps. Barry Moore and Jerry Carl. With nearly half of the expected vote now reporting, Moore leads Carl 57.5 percent to 42.5 percent. Moore's edge might come as a surprise considering Carl outraised Moore and had more outside spending help. Moreover, Carl currently represents more of the new 1st District under the old district lines. But Carl still could catch Moore thanks to his home base of Mobile County, where only 9 percent of the expected vote has reported, with Carl up 74 percent to 26 percent.

Jason Palmer’s PR team

I’m sure I’m not the only reporter who’s been receiving emails from Anderson Group Public Affairs, a PR firm flacking for Jason Palmer for several months now. I guess I should have been paying more attention before just sending them to my trash! Also, I think he’s the only candidate working with a PR firm that also sends emails with the subject line “Interview Entrepreneur Behind Billion Dollar Sex Toy Company.”

If you’re furiously Googling Jason Palmer right now …

You’re not alone. He’s currently trending on Twi—I mean X, and his campaign website appears to have crashed.

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.
