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.

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.
