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.

Reading is hard. Listen to us instead!

This is the best live blog in the industry ;), but I know you may have some chores to finish up before settling in for a night of election results. Those dishes aren’t going to wash themselves! So if you’d rather listen to our analysis, I’ve got a podcast episode for you. Nathaniel, Leah, Geoff, friend of the pod Tia Mitchell and I sat down yesterday to talk about what to expect from the top of the ticket tonight. Where might Haley overperform? And when will Trump sew up the nomination?

We also talked about Senate Minority Leader Mitch McConnell’s announcement that he’ll retire from his post this November and what that means for the direction of the Republican Party. And we discussed the political and policy chaos that has followed the Alabama Supreme Court’s decision in February that embryos are children, complicating the procurement of in vitro fertilization services in the state.

Later tonight we’ll record a podcast reacting to the Super Tuesday results, so make sure to check your feeds tomorrow morning too!
