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.

Adding to what Galen said about primary coverage

I certainly don't mean to blame my hardworking friends in the media. The view from academia is that I organized a whole class around the prospect of an exciting primary, cue the sad trombone noise. I agree with what you said, and also think this is sort of an outgrowth of the weirdness of a primary election. Is it a preliminary election with terrible turnout? A party process, but just a fairly open one? It's hard for all of us in the explaining business because it's honestly kind of a confusing thing.

Trump is projected to win Oklahoma

This is not a surprise, but ABC News projects that Trump will win the Republican primary in Oklahoma, based on an analysis of the vote. In the latest polling, he lead by nearly 80 points against Haley.

And we have a projected Dem nominee for North Carolina Governor

Josh Stein, the North Carolina attorney general, is projected to be the Democratic nominee for governor. Stein was a state senator for 7 years before running for attorney general. He has twice beat out Republican candidates, and is the first Jewish person to be elected to statewide office in the state. His race against Robinson for governor will be one of the most closely watched come November, because a Republican win would give the GOP a trifecta for the first time since 2016.

Buckhout also has an endorsement from anti-abortion group Susan B. Anthony List

I'm watching Buckhout for another reason: She has the endorsement of the influential Susan B. Anthony List. The group started out endorsing pro-life women candidates as a kind of counterpart to women-supporting, pro-choice group EMILY'S List, but during the Obama administration also focused on endorsing Republicans against some anti-abortion Democratic women. It was a powerful insider voice against Roe v. Wade, and, since the fall of Roe v. Wade, has called for a national 15-week abortion ban. Democrats will run in November telling voters that the right to abortion nationwide is at stake, and abortion is definitely playing a role in Republican primaries across the country. With 22 percent of the expected vote reporting, Buckhout is currently leading with 56 percent of the vote so far.

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.
