ABC News projects that Rep. Barry Moore will defeat fellow Rep. Jerry Carl in Alabama's 1st District GOP primary, winning the lone incumbent-versus-incumbent primary we're expecting to have this cycle.

The big races I was eyeing in North Carolina are tightening up. In the 1st District (which is set to be the only competitive Congressional race in the Tar Heel state in November), wealthy businesswoman Laurie Buckhout is projected to win the GOP nomination. The 6th District looks destined for a runoff. In the 8th District, Mark Harris (whose 2018 win was thrown out due to allegations of ballot fraud) is projected to win the Republican nomination. And in the 13th District, Kelly Daughtry, an attorney who came in third in the Republican primary in 2022, is creeping closer to the 30 percent threshold needed to avoid a runoff. Not a ton of surprises, but an interesting night downballot for sure!

The race in California's 47th District is competitive within the Democratic field where, as we've mentioned, Rep. Katie Porter decided to run for Senate, opening up her House seat. The House primary she won in 2018 to face (and eventually defeat) the Republican incumbent, Mimi Walters was also competitive. In fact, Dave Min, who is running today, was the favored Democrat in that 2018 primary, but Porter beat him out to finish second, behind Walters, and went on to win the seat. With 46 percent of the expected vote in, Min is leading his closet rival, Joanna Weiss, by about 8 points.

Redistricting made Alabama's 2nd District Democratic-leaning, and a bevy of candidates jumped into the party primary with a shot at winnable seat. But in Alabama, primary winners must win a majority, so the crowded race has made an April runoff likely. With about 80 percent of the expected vote reporting, former Justice Department official Shomari Figures leads with nearly 44 percent. ABC News has projected that Figures, the son of longtime state Sen. Vivian Figures and the late state Sen. Michael Figures, will advance to the likely runoff. The race of the second runoff spot is not set, but state House Minority Leader Anthony Daniels has 22 percent, ahead of state Rep. Napoleon Bracy's 16 percent. Daniel actually hails from Huntsville in the north of the state, far from the southern Alabama base of the district. Bracy is from Mobile, and there are still some votes left to report from there, so he can't be discounted.

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.
