ABC News now projects that Democratic Rep. Adam Schiff and Republican Steve Garvey, a former Major League Baseball player, will advance in California's U.S. Senate race. This will set up a traditional Democrat-versus-Republican contest in November, which is unlikely to be interesting in deep-blue California. With 41 percent of the estimated vote reporting, Schiff leads Garvey 37 percent to 29 percent. That suggests that Schiff's spending on ads to improve Garvey's name recognition among Republicans succeeded, allowing the congressman to avoid facing fellow Democratic Rep. Katie Porter, who is in third with 15 percent. And while we are still waiting for more returns, our map of the top-two Senate primary shows only Schiff and Garvey holding leads in any county that has results, speaking to their edge.

With all precincts reporting in North Carolina’s 8th congressional district, Baptist minister Mark Harris is winning 30.44 percent of the vote per North Carolina's State Board of Elections, successfully avoiding a runoff and securing his spot on the ballot in the solidly Republican district after ballot fraud allegations kept him out of Congress in 2018.

I've been keeping half an eye on the race for the chief justice for the state Supreme Court in Arkansas, and the four-way race is very close. With almost all of the expected vote in, two sitting justices, Justice Rhonda Wood and Justice Karen Baker, are virtually tied at about 27 percent each, according to The New York Times. If they remain the top two candidates when all the votes are in, they'll had to a runoff in November. Fun fact: Baker is from my hometown of Clinton, Arkansas.

A big question is whether Trump is line to mathematically clinch the nomination next Tuesday, March 12 — the earliest possible date on the calendar that a candidate (namely, Trump) could claim a majority of the GOP's 2,429 national delegates. And it looks like it could be close.

Trump entered the night with 247 delegates to Haley's 43, according to 538's delegate benchmark tracker, and he looks in line to win roughly 775 to 805 delegates out of 854 that were up for grabs today. That would put him at around 1,025 to 1,055 delegates. If he's on the short end of that range, a Trump sweep of all delegates in contests after today up through March 12 would put him just above the 1,215 mark to clinch. This makes the Vermont result, where Haley is just above 50 percent, pretty important, because it would mean the difference between Trump claiming about 0 delegates, or claiming 8 should Haley fall short of a majority in her victory.

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.
