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.

Allred wins the Democratic Senate nomination in Texas

Back to regularly scheduled programming ... Former Tennessee Titans linebacker and current Congressman Colin Allred is projected by ABC News to win the Democratic primary for Senate in Texas.

Allred was the favorite to win the race tonight, but the bigger challenge will be trying to unseat former Canadian and current Senator Ted Cruz this fall. As Dan noted when Cruz locked down his primary earlier tonight, Democrats are hoping that they can finish what Beto O’Rourke started in 2018, when O'Rourke came within spitting distance of flipping Cruz’s Senate seat. If Democrats' are going to flip any Senate seats, this is likely their best shot, and is an important one if they hope to maintain their narrow majority in the upper chamber. So expect to see a lot of eyes and cash on this race in the months to come.

Rubio plus Kasich shows the way for Haley in Vermont

As The Washington Post's Lenny Bronner has pointed out, Haley tends to do better in the places where mainstream or moderate Republicans Rubio and Kasich did better in 2016. In Vermont, Trump won the state in 2016, but by just over two percentage points over Kasich. And together, Rubio and Kasich won 49.7 percent of the vote in 2016, meaning that Haley needs to just about equal their joint performance to win the state. So far, she's roughly doing that. Of the 120 towns with nearly all the expected vote in, Haley's share tops Rubio's plus Kasich's in 65 towns while being under it in another 55.

No polls for Palmer

Unfortunately, we’ve seen no polling at all this cycle that includes Palmer. So there’s no way to tell how he stacks up against Trump.

Is he even real?

Jason Palmer's (currently down) campaign website features a page called PalmerAI, where a deepfaked video of today's Democratic winner in American Samoa can answer any and all questions you might have about him or his campaign. Talk about uncanny valley.

Trump pivots to the general

Trump is speaking now (right on schedule, for once!) and it's one of those "pivot to the general" speeches candidates give once they win the nomination. But it's also like he's playing his greatest hits on 1.5x speed: In the last five minutes, he has talked about immigration (saying migrants are coming in on airplanes), ISIS (he says he wiped them out in four weeks), inflation (chastising "Bidenomics") and energy generation, and he attacked Biden for his age (at one point claiming that the president cannot lift a beach chair which "weighs nine ounces").

One thing missing? Any mention of Haley. Remember, Trump is not technically the nominee until the convention says so, and he's not the presumptive nominee until he wins enough delegates. He is having a super Super Tuesday tonight, but he's not quite there ... yet.
