ABC News can now project that Trump will win the Colorado primary. With almost half the expected vote reporting already, Trump has 60 percent to Haley's 36 percent. It's Trump's eighth win of the evening already, and this one is particularly rough for Haley, as this was one of the few states where she had the best shot at an upset win.

Polls have now closed in Minnesota, which was a sleeper battleground in the 2016 general election, but tends to support Democrats. There are a greater-than-average number of college graduates in the state, which should be good for Haley, but there's also a sizable white working class population, which, if you're reading this live blog, you probably already know, is good news for Trump.

In one of the least surprising developments of the night, ABC News projects that Trump will win Alabama. Only 5 percent of the expected vote has reported there, but Trump leads Haley by a punishing 69-point margin, 83 percent to 14 percent. We expected Alabama to be one of Trump's strongest states, and that looks to be the case.

Going into tonight, I thought that Colorado could be a dark horse state for Haley. There wasn't a single poll of the race there, and the state's highly educated demographics seemed like a good fit for her.

Well, so far, it ain't happening. With 28 percent of the expected vote reporting, Trump is taking 57 percent of the vote there, while Haley has just 40 percent.

Tonight I'll also be watching my home state of Arkansas, where polls just closed. There hasn't been recent polling on the GOP presidential primary there, but Trump remains popular in the conservative state, which he won 62 percent of the state in the 2020 general election. His former press secretary is the governor, Gov. Sarah Huckabee Sanders, and she endorsed him in the fall.

There's not much suspense downballot either. Rep. Steve Womack, who represents the northwest corner of the state—home to the University of Arkansas, Walmart, and other big businesses and booming towns—is fending off an unlikely challenger from his right and is the only Republican incumbent to face a challenger. That challenger, State Sen. Clint Penzo is against vaccines, the war in Ukraine, government spending and has criticized Womack's votes during the House speaker fight last fall. But Womack has represented the district for 13 years and all the advantages of incumbency.

On the Democratic side, all four candidates for the House are running uncontested.

Perhaps of a bit more interest — earlier, I wrote about the state Supreme Court races and how the outcomes there could result in a game of musical chairs leading the very conservative Sanders to make one or two appointments to the court.
