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.

On Sunday, Republicans in Washington, D.C., voted for Haley by nearly 30 percentage points in the GOP's party-run primary, giving her all 19 national delegates from the nation's capital. This marked her first victory anywhere in this year’s primary contest, and the first ever primary or caucus victory for a woman in the history of Republican nomination races. Yet the other contests that took place just ahead of Super Tuesday otherwise showcased Trump's strong hold over his party's base. This included victories on Saturday in caucus-convention races in Idaho, Michigan and Missouri, and in North Dakota's Republican caucuses on Monday.

In Michigan, Republicans gathered at Saturday's state party convention to allocate 39 national delegates from the state’s 13 congressional districts (three per district). The voters consisted of precinct delegates mostly elected at the August 2022 state primary as well as Republican elected officials, and they handed Trump all 39 district-level delegates. This result brought Trump's Michigan haul to 51 of the state's 55 delegates, after he had already won 12 of its 16 at-large delegates in the Feb. 27 primary.

The Michigan GOP's split primary-caucus approach came about in part because national Democrats added Michigan to the early part of their presidential primary calendar, prompting the Democratic-controlled state government to shift the state’s primary date into late February. Since the new date violated the national GOP's calendar rules, Michigan Republicans used a workaround whereby the primary results would allocate the state's at-large national delegates, but the state party didn’t formally make the allocation until March, at Saturday’s caucus-convention that also allocated district-level delegates.

Trump also swept caucuses in Idaho and Missouri on Saturday, and then North Dakota on Monday. In Idaho, Trump won 85 percent of caucusgoers, easily surpassing the state's 50 percent winner-take-all threshold to capture all 32 of Idaho's national delegates. In Missouri, Trump won every state- and congressional district convention delegate elected at local caucuses around the state, all but guaranteeing that he will sweep all 51 national delegates when the district and state conventions formally allocate delegates in April and May, respectively. And in a near-repeat of Idaho, Trump won 84 percent of caucusgoers in North Dakota on Monday to claim all 29 of the state’s national delegates.
