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.

A projection in California's 30th District

Good morning! We continue to track the handful of House races that still don't have winners, mostly in California. As a reminder, California votes almost entirely by mail, and while ballots had to be postmarked by March 5, they can arrive as late as March 12 and still count. Therefore, there are still thousands of ballots out there to be counted, so we could be waiting for several days.

In the meantime, though, we can cross one unresolved congressional race off the list: In California's 30th District, ABC News reports that Democrat Laura Friedman and Republican Alex Balekian are projected to advance to the general election in November. The 30th District is the seat that Schiff is leaving behind to run for Senate, and it's safely Democratic, so Friedman, a former film producer and state assemblywoman, should have no problem winning in the fall. The primary result is kind of a lucky break for her, actually, as there was a chance that she was going to face a fellow Democrat like Anthony Portantino or Mike Feuer in November, which would have been a dogfight.

P.S. People with long memories might remember that "Boy Meets World" star Ben Savage was also running for this seat, but he ended up finishing seventh with just 4 percent.

The field is set in California's 47th and 49th

ABC News is also projecting the general-election candidates in two California House races:

- In the 47th District, Republican Scott Baugh and Democrat Dave Min have advanced out of the top two primary, leaving Democrat Joanna Weiss out in the cold. This is the seat that Democratic Rep. Katie Porter vacated to run for Senate, and it will be tough for Democrats to defend. Some Democrats are worried that Min's DUI arrest last year could drag him down.

- In the 49th District, Democratic Rep. Mike Levin and Republican Matt Gunderson have advanced to the general election. Biden carried this district by 11 points in 2020, so it'll probably stay in Democratic hands, but it's not out of the question that Gunderson could win in the fall.

More runoffs projected in Texas, North Carolina

Catching up on some ABC News race projections that we missed earlier:

- In the Republican primary for North Carolina's 13th District, ABC News projects that Kelly Daughtry and Brad Knott will advance to a May 14 runoff. This is currently a Democratic-held seat, but the GOP legislature redrew it to be safely Republican, so whoever wins the runoff should be a shoo-in in November.

- In the Republican primary for Texas's 12th District, ABC News projects that Craig Goldman and John O'Shea will advance to a May 28 runoff. This is a solidly red open seat currently represented by retiring Rep. Kay Granger.

- And a bit of a surprise in the Republican primary for Texas's 23rd District: incumbent Rep. Tony Gonzales garnered just 45 percent of the vote, forcing him into a runoff with second-place finisher Brandon Herrera. Gonzales was censured by the Texas GOP last year for supporting bipartisan gun legislation in the wake of the shooting in Uvalde, which is in his district. Clearly, the GOP base is still not happy with him.

Several incumbents ousted in the Texas state House

As we explained yesterday, Texas Gov. Greg Abbott, Texas Attorney General Ken Paxton and Trump all set out to defeat several incumbent Republicans in the Texas state House yesterday (albeit for different reasons). The Associated Press has now projected winners in most of those races, and here's how they turned out: In total, at least eight Republican incumbents lost their primaries after being targeted by one of those three men. Another seven, including Speaker Dade Phelan, were forced into runoffs.

Abbott's muscle looks like it was the most effective: Five of the 10 incumbents he targeted (over their opposition to his school-voucher plan) lost, and another three went to runoffs. Trump also did OK: Two of the eight incumbents he targeted lost, and three more went to runoffs. Paxton didn't have as high of a success rate: Only seven of the 35 incumbents he targeted lost, although seven more were forced into runoffs. That's maybe not too surprising, though, since unlike Abbott, Paxton didn't put a ton of money where his mouth was.
