In the early primaries and caucuses on the GOP side, a few patterns became clear. Donald Trump marched toward the nomination by winning most groups of Republican primary voters, but Haley proved a bit more competitive in pockets with large numbers of college-educated voters. Trump has expanded his 2016 coalition by winning more voters on the right, which we can see by his strength in places where Ted Cruz did well eight years ago. Haley, meanwhile, competes among moderates. Tonight, that meant dominant wins for Trump across a set of states, from Virginia and North Carolina to Texas and California. Among tonight's states, Virginia's demographics make it more friendly to non-Trump candidates — Rubio almost won it in 2016 — so Haley's failure to breech 40 percent there is yet another sign that she's able to win only a minority faction within today's GOP.

Overall, there isn't much surprise in tonight's Republican presidential results, beyond the question of whether Haley will eke across the 50 percent threshold and so take home all of Vermont's delegates. In part, that reflects the nationalization of presidential politics. In state after state, the same kinds of communities lean towards or away from Trump, so the results follow pretty consistently from a state's demographics and prior voting behavior. That makes for predictable patterns — and a less than surprising Super Tuesday.

Thinking about what Kaleigh said, the fact that Trump and Biden have their primary races all but sewn up does make for some blah primary election nights. That's why all the attention shifted to Vermont, which Haley is likely to win, and to American Samoa on the Democratic side, where we all learned that someone named Jason Palmer had been running all along. I'm like Mary and ready to turn to the general election, when we can focus on how Biden and Trump are appealing to voters and what the consequences of their stances and potential victory might be.

On the presidential side, tonight basically went as expected: Trump will win at least 12 out of 15 contests, while Haley has chalked up only one win so far — a narrow win in Vermont, which was demographically well suited for her as it is home to a lot of independent voters, a lot of college graduates and few evangelicals. Trump also now leads the delegate race 908 to 62, as of midnight.

The question is, what will Haley do now? She has said all along that she wanted to give the voters on Super Tuesday a chance to weigh in on the race, and they did so, roundly rejecting her. She's now so far behind in the delegate race that she can't credibly say she still has a path to the nomination. She has no more public events scheduled, so it seems quite possible that she will drop out of the race, but we haven't heard from her so far tonight. Might she sleep on it and announce her withdrawal from the race later on Wednesday? That's really the only suspense left in this presidential primary.

As we discussed earlier, using presidential primary results to read the tea leaves of the general election seems to be a particularly fraught exercise. The dynamics (and electorates) of the two types of contests are wildly different, and several of my colleagues pointed out a variety of ways in which this type of analysis could go awry.

But now that Biden and Trump are both within weeks of officially securing their party nomination, I wonder if we'll start to see the conversation around the election turn. As Elliott noted earlier, Trump's speech tonight sounded more like a pivot to the general: Rather than mentioning Haley, he focused on Biden. And with the State of the Union on Thursday, Biden will also have an opportunity to try to focus the nation on his priorities for a potential second term. So it seems like both Trump and Biden have an opportunity to try to start communicating with the nation on their respective visions for the country.

The wildcard, for me, is whether voters are ready to pay attention. If they're not, then the messaging coming from the two candidates might start to turn into a low hum of background noise, essentially taking the edge off of any possible messaging wins as the campaigns beat the same drums for 8 straight months. If voters are ready to tune in, though, we may start to see polls shift in one direction or the other as campaigning begins in earnest.

As we wait for the final winners of Super Tuesday's primaries to be projected, here's where things stand in the races we're tracking:

- California's 16th District: With 57 percent of the expected vote reporting, Democrat Sam Liccardo has 22 percent, Democrat Joe Simitian has 18 percent, Democrat Evan Low has 16 percent and Republican Peter Ohtaki has 13 percent. This is a solid blue district, so we expect two Democrats to advance to the general election.

- California's 20th District: ABC News has projected that Republican Vince Fong (currently at 39 percent with 52 percent of the expected vote counted) will take one of the general-election slots, but the other is still up for grabs between Republican Mike Boudreaux (25 percent) and Democrat Marisa Wood (22 percent).

- California's 22nd District: With 50 percent of the expected vote counted, Republican incumbent David Valadao has 34 percent, Democrat Rudy Salas has 28 percent, Republican Chris Mathys has 22 percent and Democrat Melissa Hurtado has 15 percent. Democrats were afraid of getting shut out of the general election in this swing seat, but that doesn't look likely to happen now.

- California's 31st District: Democrats should maybe be more worried about a lockout in this open, safely Democratic seat. With 70 percent of the expected vote in, Democrat Gil Cisneros has 21 percent, Republican Daniel Martinez has 21 percent and Republican Pedro Casas has 19 percent.

- California's 45th District: ABC News has projected that Republican Rep. Michelle Steel will advance to the general; she has 57 percent of the expected vote with 82 percent reporting. Her November opponent will either be Democrat Derek Tran (16 percent) or Democrat Kim Nguyen-Penaloza (14 percent).

- North Carolina's 8th District: With 97 percent of the expected vote in, Republican Mark Harris is at 30.4 percent, just barely above the threshold to avoid a runoff. The Associated Press has already declared him the winner.

- Texas's 32nd District: Similarly, with 99 percent of the expected vote in, Democrat Julie Johnson is at 50.4 percent, which would just barely be enough to avoid a runoff. If she does face one, it would be against fellow Democrat Brian Williams, who is at 19 percent of the vote.
