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.

Republican women of North Carolina

Earlier I wrote that although more Republican women are running, the GOP conference is still largely represented by men. North Carolina, where polls just closed, nicely illustrates some of the reasons that Republican women continue to trail Democratic women by such large margins, in Congress. North Carolina has low female representation in their state legislature (which is just 29 percent female), and that limits their recruitment from that pool. And in today's open primaries in safely Republican districts where the GOP primary will effectively decide the next representative, women aren't among the most competitive. As Kaleigh wrote earlier, in the 8th District outside Charlotte, the two GOP front runners are state Rep. John Bradford, and Baptist minister Mark Harris. And in the 10th District, the race is largely between state Rep. Grey Mills and Pat Harrigan, a gun manufacturer. There are several non-incumbent women running in the state today, but none of the groups we are watching that support Republican women (Winning for Women, VIEW-PAC, E-PAC or Maggie's List) have made endorsements.
