Overnight last night, ABC News projected that firearms manufacturer Pat Harrigan will be the GOP nominee in North Carolina's 10th District. He defeated more conservative Republican Grey Mills 41 percent to 39 percent. The 10th District is a solidly red seat currently represented by retiring Rep. Patrick McHenry, and Harrigan should have no trouble winning it in the fall.

Last night, the "uncommitted" campaign made headway in a few more states. After a protest vote for Biden's response to Israel's war against Gaza helped net over 100,000 uncommitted votes in last week's Michigan Democratic primary, supporters of the Listen to Michigan campaign expanded their efforts to other states with "uncommitted" or similar language as an option on primary ballots.

With 89 percent of the expected vote reporting, 19 percent of Democratic primary voters in Minnesota voted uncommitted, eclipsing the 13 percent reached last week in Michigan. That means "uncommitted" will send at least 8 (and up to 11) delegates from Minnesota to the Democratic National Convention in August, per the latest ABC News projections.

"No preference" also garnered 13 percent of ballots cast in North Carolina and 9 percent in Massachusetts, while 8 percent of primary voters in Colorado chose "noncommitted." However, those aren't enough to meet their respective states' thresholds to send a delegate to the national convention. (That's 15 percent in all three of those states.)

While Haley called on Trump to earn Republicans' votes, Mitch McConnell suggested that he already has. "It is abundantly clear that former President Trump has earned the requisite support of Republican voters to be our nominee for President of the United States," McConnell said in a statement. The rest was pretty standard endorsement fare, going on to tout Trump's accomplishments on tax reform and judicial appointments, and criticizing Biden.

It's an undramatic end to the minor drama over whether the soon-departing majority leader would endorse Trump, with whom he's undoubtedly had a rocky relationship. In the end, McConnell waited until just after Trump's final major opponent dropped out to fall in line. With one of the last major (potential) party holdouts in his corner, the general election train is in full swing for Trump.

According to the latest numbers from our colleagues at ABC News, Trump has 1,051 of the 1,215 delegates he needs to mathematically clinch the Republican nomination for president. Haley's withdrawal from the race puts him on track to reach that magic number next Tuesday, March 12. A total of 199 delegates will be allocated between now and then, and presumably Trump will win all or almost all of them.

Voters are choosing more than their parties' presidential nominees tonight. In five Super Tuesday states, they're also deciding on candidates for statewide and local offices. Several consequential judicial elections are being held tonight, for positions on state supreme courts in Alabama, Arkansas and Texas, and on the Criminal Court of Appeals in Texas.

In Arkansas, nonpartisan general elections are being held to fill two vacancies on the Supreme Court, creating a game of musical chairs among the sitting justices that could potentially accelerate the already-conservative court's rightward shift. Chief Justice Dan Kemp is stepping down, and three of the four candidates running to replace him are already sitting on the court, while another sitting justice is angling to move to a different open seat on the court. The shuffle could leave two vacancies that would allow conservative Gov. Sarah Huckabee Sanders to name replacements to finish their terms.

Alabama's Supreme Court Chief Justice Tom Parker, who recently made waves nationally with a ruling that frozen embryos used for IVF are children, is also retiring because of the state's mandatory retirement age. Two candidates are running for the Republican nomination to replace him: sitting Associate Justice Sarah Stewart (who had to give up her seat to run for the top slot) and former state Senator Bryan Taylor. While Stewart joined the 8-1 majority opinion in the IVF case and both candidates have defended the decision, Taylor has claimed that Stewart is the "most liberal" justice on the all-Republican court, and received a huge influx of outside spending from conservative anti-abortion group Fair Courts America. Whoever wins will likely face (and defeat) Democrat Greg Griffin>) in the general election.

In Texas, Supreme Court Justice John Devine is facing a primary challenger who has questioned his ethics, but a bigger political feud is playing out in other races. Allies of Republican Attorney General Ken Paxton are funding primary challengers to three Criminal Court of Appeals judges who ruled against him in a voter fraud decision, limiting his power to prosecute those cases. And as Nathaniel noted earlier, Paxton, who had been accused of abusing power to protect a political donor, has also endorsed primary challengers against 34 of the 60 Republican legislators who voted to impeach him last year.
