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.

The race for Senate in Texas will surely be one of the most closely watched races of the year. There are nine candidates running in the Democratic primary to unseat Sen. Ted Cruz, but the front-runner is Rep. Colin Allred, a former NFL player and civil rights attorney who has represented the Dallas area since 2019. Allred has raised the most funds (to the tune of $21 million) and attracted donations from party influencers. The biggest question tonight is whether Allred can pull more than 50 percent of the vote and avoid a May runoff.

There are also a handful of U.S. representatives in Texas with at least some danger of losing their seats tonight, as Jacob covered earlier. Keep your eyes on Houston Democrat Lizzie Fletcher in the 7th District, who is facing a challenger from the left in Pervez Agwan; Democrat Sheila Jackson Lee in the 18th District, whose run for Houston mayor last year destabilized her campaign against former Houston City Councilwoman Amanda Edwards; and Republican Tony Gonzales in the 23rd District, who is facing multiple challengers and may also end up in runoff territory.

And there are some open seats up for grabs, creating hotly contested primary races. In the 12th District around Fort Worth, it's the familiar GOP battle between results-focused conservatism of the old guard versus the firebrand populism of MAGA. State Rep. Craig Goldman represents the establishment candidate, while business owner John O'Shea fills the role of MAGA candidate. In the 26th District, two far-right candidates are leading a slate of 11 to fill the open seat in this deep-red stronghold: Brandon Gill, who heavily promoted his father-in-law, Dinesh D'Souza's, conspiracy-theory-laden film "2000 Mules" on his website, and Southlake Mayor John Huffman. And lastly, with Allred making a play for the Senate, his Dallas-area 32nd District is up for grabs. Ten Democrats are running in the primary, though two in particular seem to be leading the pack: state Rep. Julie Johnson and trauma surgeon Brian Williams.
