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.

Downballot, Trump’s endorsees are winning in Texas

As Nathaniel and I discussed earlier, dynamics in the Texas state legislative elections have been particularly contentious this year, with the governor and Trump endorsing at least eight challengers to Republican incumbents in the state House. As of now, seven of those challengers are currently leading their primaries, though a few look headed to a runoff. One challenger, Barry Wernick in the 108th, is trailing by just 2 points.

It’s ovah in Minnesota

ABC News projects that Biden will win the Minnesota Democratic primary, and Trump will win the Republican primary. Biden’s win is expected, but also salt in the wound for his highest-profile competitor, Minnesota Rep. Dean Phillips, who gave up a safe seat in Congress and the potential for a strong statewide run in a few years to launch his no-shot challenge against Biden.

Trump projected to win Massachusetts

ABC News projects that Trump will win the Massachusetts primary, his 10th win of the evening. With 15 percent of the expected vote reporting, Trump is leading Haley in the Bay State 59 percent to 37 percent. Yet again, this is another state where Haley was hoping to do well: Massachusetts has a lot of college graduates, and it allows independents and Democrats to vote in the Republican primary. But with Trump’s win, the Haley campaign turns its lonely eyes to Vermont.

Trump opens up lead in Vermont

With 56 percent of the expected vote now reporting, Trump has opened up a bit of a lead against Haley in Vermont. He has half the vote, and Haley is just behind him with 47 percent. Still, that's closer than the two polls, had us expecting. There's still room for Haley to pull out a win, which she would need: all of the state's 17 primary delegates go to the winner. That is, unless they both end up with under 50 percent of the vote, in which case they split the delegates proportionally.

Voters are choosing candidates for 7 of the 15 seats on the powerful Los Angeles City Council

In Los Angeles, voters will decide which candidates will face off in November for seven of its 15 city council seats. Arguably one of the most powerful city councils in the country, it's been riddled with scandal the past few years.

In 2022, leaked audio revealed then-City Council President Nury Martinez making racist comments in a meeting that included two other council members, which ultimately led to her resignation. One of the other members who was part of that conversation, Kevin de León, remains on the council after surviving months of protests, calls for his resignation (including from President Biden) and a recall attempt. Today he's running for a second four-year term against seven challengers, including two former political allies, state Assemblymembers Miguel Santiago and Wendy Carrillo. Santiago specifically has scooped up the endorsement of the key labor unions that once backed de León, as well as the Los Angeles County Democratic Party.

Overall, policing, affordable housing and homelessness are big issues in the city, the second largest in the nation, and how the council decides to handle those issues in the future could help set the tone for the rest of the country. Today's elections could help decide, in part, how progressive the council will be: In other races, business interests have been targeting progressive Councilmember Nithya Raman, and spending to bolster the council's only non-Democrat, independent John Lee, who faces an ethics probe and a more progressive challenger.
