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.

Latest headlines:

  • That's a wrap!
  • New projections in California's 20th and 31st
  • No runoff after all in North Carolina's 6th
  • Some projections in California
  • Biden and Trump are officially presumptive nominees
Here's how the news is developing.

That's a wrap!

Well, reader, we were determined to keep this live blog going until every Super Tuesday race had been resolved, but even we have our limits. In preparation for next week's primary live blog, we're wrapping this one up. Here's where things stand in all the races we're still tracking:

- With 99 percent of the expected vote reporting in California's 16th District, we're still not sure who will join Democrat Sam Liccardo in the general election. Democrat Evan Low and Democrat Joe Simitian both currently have 17 percent of the vote, and Low is just 63 votes ahead of Simitian.

- With 99 percent of the expected vote reporting in California's 45th District, Republican Rep. Michelle Steel is a safe bet to advance, but it's a close race for second. Democrats Derek Tran and Kim Nguyen-Penaloza are both at 16 percent, with Tran just 256 votes ahead.

- With 98 percent of the expected vote reporting in the Republican primary for North Carolina's 8th District, Mark Harris is at 30.4 percent, just above the 30 percent threshold he needs to avoid a runoff. The AP has gone ahead and called the primary for Harris, but ABC News has not yet reported whether Harris will win outright or be forced into a runoff.

- With 99 percent of the expected vote reporting in the Democratic primary for Texas's 32nd District, Julie Johnson is similarly hovering at 50.4 percent, which would just barely be enough to avoid a runoff. While the AP has called this race for Johnson, ABC News has not yet reported whether a runoff will be needed.

New projections in California's 20th and 31st

We've got answers on two California House races that were still outstanding! In California's 20th District, ABC News reports that Republican Mike Boudreaux will make the general election, where he will face fellow Republican Vince Fong (who was already projected to advance). It's no surprise that no Democrats made the general election here, as this is the reddest seat in California. (It used to be represented by Kevin McCarthy.)

Similarly, in California's 31st District, ABC News reports that Republican Daniel Martinez will advance to the general election, joining Democrat Gil Cisneros (who was already projected to advance). That's good news for Cisneros; since this is a solidly blue seat, he will have no trouble in the general election against Martinez, whereas he would've faced a tougher campaign against a fellow Democrat.

No runoff after all in North Carolina's 6th

Various news organizations (including ABC News) had projected that Republicans Addison McDowell and Mark Walker would advance to a runoff election in North Carolina's 6th District. However, that contest has now been called off. According to Spectrum News's Reuben Jones, Walker is taking a job with Trump's campaign and will not request a runoff after all. (In North Carolina, the second-place finisher has to request a runoff, it doesn't happen automatically.)

This maneuver is probably not a coincidence given that Trump endorsed McDowell in December. Regardless, it means that McDowell will be the GOP nominee here and very likely the district's next congressman, since Trump carried the 6th District by 16 points in 2020.

Some projections in California

The general-election candidates are set in one of this fall's most competitive House races. ABC News reports that in California's 22nd District, Republican Rep. David Valadao and Democrat Rudy Salas are projected to advance to the general election, setting up a rematch of the 2022 race that Valadao won by just 3 points.

In addition, ABC News reports that Democrat Sam Liccardo and Democrat Gil Cisernos are projected to make the general election in California's 16th and 31st districts, respectively. Their general-election opponents, however, are still TBD.

Tracking an anti-abortion group's candidates

I mentioned this earlier, but I'm tracking candidates endorsed by the anti-abortion Susan B. Anthony List. So far, the group can claim two likely victories: North Carolina House Speaker Tim Moore in North Carolina's 14th District and Rep. Mayra Flores in Texas's 34th District. Buckhout is leading in her race for the 1st District in North Carolina. The only Susan B. Anthony List endorsee we're tracking tonight who is trailing is state Rep. Grey Mills, who's in second place behind Rep. Pat Harrington. Harrington dropped a bid for the 14th District, where he would have faced Moore, to switch to the 10th. The 10th District's incumbent, Patrick McHenry, is not seeking reelection.
