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.
In one of the least surprising developments of the night, ABC News projects that Trump will win Alabama. Only 5 percent of the expected vote has reported there, but Trump leads Haley by a punishing 69-point margin, 83 percent to 14 percent. We expected Alabama to be one of Trump's strongest states, and that looks to be the case.

Going into tonight, I thought that Colorado could be a dark horse state for Haley. There wasn't a single poll of the race there, and the state's highly educated demographics seemed like a good fit for her.
Well, so far, it ain't happening. With 28 percent of the expected vote reporting, Trump is taking 57 percent of the vote there, while Haley has just 40 percent.

Texas Republican Rep. Dan Crenshaw has long had a bit of a fractious relationship with the more extreme members of his party. He was one of just a few Republicans to vote to certify Biden's election in 2020, and he's often feuded with fellow Republican, Georgia's Marjorie Taylor Greene. Though he's been a reliable vote against the Biden agenda and is backing Trump again, co-hosting a fundraiser for the former president, he's clearly not alright with the base.
With about 73 percent of the vote reporting, he leads his conservative challenger Jameson Ellis by just 17 points. That might seem like a lot, but consider that just two years ago, Crenshaw also faced Ellis in the 2022 GOP primary and defeated him by a much wider 58-point margin.

Democratic Rep. Sheila Jackson Lee is projected to win the Democratic primary in Texas's 18th District, fending off a challenge from former Houston City Councilwoman Amanda Edwards. Jackson Lee lost a bit of steam in her congressional campaign by running for Houston mayor last year, a race she lost. But after jumping back into her reelection bid, she has managed to edge out the young upstart challenger in Edwards, all but guaranteeing her another term in this deep-blue district.
