Time for our first update of what's happening in the Republican primary in Alabama's 1st District. There, court-ordered redistricting precipitated an incumbent-versus-incumbent contest between Reps. Barry Moore and Jerry Carl. With nearly half of the expected vote now reporting, Moore leads Carl 57.5 percent to 42.5 percent. Moore's edge might come as a surprise considering Carl outraised Moore and had more outside spending help. Moreover, Carl currently represents more of the new 1st District under the old district lines. But Carl still could catch Moore thanks to his home base of Mobile County, where only 9 percent of the expected vote has reported, with Carl up 74 percent to 26 percent.

I’m sure I’m not the only reporter who’s been receiving emails from Anderson Group Public Affairs, a PR firm flacking for Jason Palmer for several months now. I guess I should have been paying more attention before just sending them to my trash! Also, I think he’s the only candidate working with a PR firm that also sends emails with the subject line “Interview Entrepreneur Behind Billion Dollar Sex Toy Company.”

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.
