While we like to think of Vermont as the home of Ben & Jerry’s and Bernie Sanders, from a historical perspective, it’s actually among the most Republican states in American history. It voted for every Republican candidate for president from 1856 to 1988 (except for Lyndon Johnson’s landslide in 1964), and former Sen. Pat Leahy was fond of noting that he was the only Democrat the state had ever sent to the Senate. So there’s something poetic about the state asserting itself in a GOP primary tonight.

Polling of the Vermont Republican primary was pretty thin this year, with only one poll released in the last month from the University of New Hampshire Survey Center. That survey suggested a fairly easy win for Trump; he was ahead of Haley by 30 percentage points. In addition, 58 percent of likely GOP primary voters in the state said they would be dissatisfied or angry if Haley were to win the nomination, while just 29 percent said the same of Trump.

Remember, dear reader, the presidential primary is all about the delegates. So far Trump has 276 to Haley's 43. That total is so lopsided that the only real question left is when, not if, Trump will win. The next big primary day is March 12 — let's take a look at what Trump needs to do today in order to clinch the delegate majority of 1,215 on the 12th.

Here's the math: There are 199 delegates up for grabs in contests between March 8 and March 12. Assuming he wins all of those 199 delegates, he would need to win 1,215 - 199 = 1,016 by the time all Super Tuesday ballots are counted. As noted, he's already won 276 of those delegates, meaning he has to pick up 769 delegates more, out of the 865 delegates up for grabs tonight. That's about 89% — which is a little higher than the 87% of delegates he has won from states that have voted so far.

Trump could totally pull that off, in which case we would start calling him the "presumptive nominee" next Tuesday. Otherwise, he will have to wait until March 19, when there are 370 more delegates up for grabs.

If you feel like sitting on the edge of your seat, like we do, The New York Times Needle is back in action tonight and has Haley ever-so-slightly ahead in Vermont at the moment.

The presidential primaries are, for all intents and purposes, over. That means we can finally shift our focus to the primaries that are going to have the most impact on the outcome in November, in the House and Senate. Tonight we saw the first of those contests, and they did not disappoint. In Alabama, an appropriator, Rep. Jerry Carl, lost to a firebrand colleague, Barry Moore, in a member versus member primary. (Let's see what that does to morale in the GOP conference.) In California, Adam Schiff successfully engineered an uncompetitive general election against Republican Steve Garvey, freeing up tens of millions in small donor dollars for races elsewhere around the country. In North Carolina, a bevy of upcoming runoffs will help determine what shape the next House GOP conference takes. And in Texas, we're going to find out in the 23rd District just how much deviation from party orthodoxy is tolerated, when Tony Gonzales faces the music for his votes on a gun bill (negotiated by the state's own senior GOP senator!). Presidential season may be over, but the fun is just beginning.
