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.

ABC News projects Haley will win Vermont

And now ABC also projects that Haley will win Vermont. The race remains super close, however, and it’s not yet clear how delegates will be awarded.

California voters don’t view either party favorably

Polls have now closed in California, where all parties run on a single primary ballot (other than in presidential races). Unfortunately, neither party is particularly popular in the state. According to a February survey from the Public Policy Institute of California, likely primary voters in California don’t have a favorable view of either political party: The Democratic party is underwater by 10 percentage points, with 44 percent of likely voters saying they have a favorable impression of the party and 54 percent saying they have an unfavorable view. The Republican party fares even worse, with a net favorability of -55 points, 22 percent favorable and 77 percent unfavorable.

Haley likely to win Vermont, but the critical margin is still up in the air

The New York Times and the Associated Press have projected that Haley will win the Republican primary in Vermont, making it the second win for her after Washington, D.C. (ABC News has not yet made a projection in this race.)

While Trump remains ahead on the delegate count, the win could give some juice to her campaign. She's vowed to stay in because she says that Trump and Biden are both too old and out of touch, and she has been capturing a sizable minority of primary voters who are unhappy with the former president in many states across the country. Still, she'll need to get a majority of the final vote to take all of the delegates, and that remains up in the air. With 92 percent of the expected vote in, she has 49.7 percent to Trump's 46 percent. If neither candidate reaches 50.1 percent, they'll split the state's delegates.

Heading to a runoff in North Carolina’s 13th?

North Carolina’s 13th District is yet another Democratic-held seat that North Carolina Republicans redrew this year to be safely red. Unsurprisingly, the GOP primary attracted a wide field, and with 67 percent of the expected vote counted according to the Associated Press, attorney Kelly Daughtry is in first place with 29 percent, followed by former federal prosecutor Brad Knott with 18 percent, businessman DeVan Barbour with 17 percent and yet another businessman Fred Von Canon with 16 percent. As a reminder, if no one gets 30 percent, the runner-up is entitled to request a runoff.

6 downballot races to watch in Texas

The race for Senate in Texas will surely be one of the most closely watched races of the year. There are nine candidates running in the Democratic primary to unseat Sen. Ted Cruz, but the front-runner is Rep. Colin Allred, a former NFL player and civil rights attorney who has represented the Dallas area since 2019. Allred has raised the most funds (to the tune of $21 million) and attracted donations from party influencers. The biggest question tonight is whether Allred can pull more than 50 percent of the vote and avoid a May runoff.

There are also a handful of U.S. representatives in Texas with at least some danger of losing their seats tonight, as Jacob covered earlier. Keep your eyes on Houston Democrat Lizzie Fletcher in the 7th District, who is facing a challenger from the left in Pervez Agwan; Democrat Sheila Jackson Lee in the 18th District, whose run for Houston mayor last year destabilized her campaign against former Houston City Councilwoman Amanda Edwards; and Republican Tony Gonzales in the 23rd District, who is facing multiple challengers and may also end up in runoff territory.

And there are some open seats up for grabs, creating hotly contested primary races. In the 12th District around Fort Worth, it's the familiar GOP battle between results-focused conservatism of the old guard versus the firebrand populism of MAGA. State Rep. Craig Goldman represents the establishment candidate, while business owner John O'Shea fills the role of MAGA candidate. In the 26th District, two far-right candidates are leading a slate of 11 to fill the open seat in this deep-red stronghold: Brandon Gill, who heavily promoted his father-in-law, Dinesh D'Souza's, conspiracy-theory-laden film "2000 Mules" on his website, and Southlake Mayor John Huffman. And lastly, with Allred making a play for the Senate, his Dallas-area 32nd District is up for grabs. Ten Democrats are running in the primary, though two in particular seem to be leading the pack: state Rep. Julie Johnson and trauma surgeon Brian Williams.
