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.

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.
