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.

Tracking the Israel-Hamas war's effect on the primary

In the Democratic primary for the Texas’s 15th Congressional District, Michelle Vallejo is leading with 32 percent of the expected vote in. She ran unsuccessfully for the seat in the 2022 midterms, but she’s leading her opponent, John Villarreal Rigney, 73 percent to 27 percent, according to The New York Times. Villarreal Rigney tried to run as the more conservative candidate, but Vallejo has the endorsement of much of the Democratic establishment and the pro-Israel group, Democratic Majority for Israel, or DMFI. AIPAC has endorsed her Republican opponent, the current incumbent, Rep. Monica de la Cruz. If Democrats can flip any seat in Texas, this is a likely one, making this race potentially competitive in November. Both AIPAC and DMFI have invested on the Democratic side to try to fend of progressive, anti-war challengers in Congress.

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.
