Super Tuesday primaries 2024: Trump and Biden dominate, Haley drops out

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.

While we're still tracking a few lingering House races from Super Tuesday, four more states — Georgia, Hawaii, Mississippi and Washington — held presidential nominating contests yesterday, enabling both Biden and Trump to cross a significant milestone. According to ABC News's delegate estimates, last night Biden passed 1,968 delegates, mathematically clinching him the Democratic nomination. Similarly, Trump last night passed 1,215 delegates, mathematically clinching him the Republican nod.

As we wait for the final winners of Super Tuesday's primaries to be projected, here's where things stand in the races we're tracking:

- California's 16th District: With 57 percent of the expected vote reporting, Democrat Sam Liccardo has 22 percent, Democrat Joe Simitian has 18 percent, Democrat Evan Low has 16 percent and Republican Peter Ohtaki has 13 percent. This is a solid blue district, so we expect two Democrats to advance to the general election.

- California's 20th District: ABC News has projected that Republican Vince Fong (currently at 39 percent with 52 percent of the expected vote counted) will take one of the general-election slots, but the other is still up for grabs between Republican Mike Boudreaux (25 percent) and Democrat Marisa Wood (22 percent).

- California's 22nd District: With 50 percent of the expected vote counted, Republican incumbent David Valadao has 34 percent, Democrat Rudy Salas has 28 percent, Republican Chris Mathys has 22 percent and Democrat Melissa Hurtado has 15 percent. Democrats were afraid of getting shut out of the general election in this swing seat, but that doesn't look likely to happen now.

- California's 31st District: Democrats should maybe be more worried about a lockout in this open, safely Democratic seat. With 70 percent of the expected vote in, Democrat Gil Cisneros has 21 percent, Republican Daniel Martinez has 21 percent and Republican Pedro Casas has 19 percent.

- California's 45th District: ABC News has projected that Republican Rep. Michelle Steel will advance to the general; she has 57 percent of the expected vote with 82 percent reporting. Her November opponent will either be Democrat Derek Tran (16 percent) or Democrat Kim Nguyen-Penaloza (14 percent).

- North Carolina's 8th District: With 97 percent of the expected vote in, Republican Mark Harris is at 30.4 percent, just barely above the threshold to avoid a runoff. The Associated Press has already declared him the winner.

- Texas's 32nd District: Similarly, with 99 percent of the expected vote in, Democrat Julie Johnson is at 50.4 percent, which would just barely be enough to avoid a runoff. If she does face one, it would be against fellow Democrat Brian Williams, who is at 19 percent of the vote.

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.
