Nathaniel just mentioned Nikki Haley's strength in the well-educated, affluent communities around Boston. If you want to learn more about that group, its connection to the defense industry, its ambivalent views on racial integration, and its long-term movement into the Democratic coalition, check out historian Lily Geismer's book "Don't Blame Us".

Trump is speaking now (right on schedule, for once!) and it's one of those "pivot to the general" speeches candidates give once they win the nomination. But it's also like he's playing his greatest hits on 1.5x speed: In the last five minutes, he has talked about immigration (saying migrants are coming in on airplanes), ISIS (he says he wiped them out in four weeks), inflation (chastising "Bidenomics") and energy generation, and he attacked Biden for his age (at one point claiming that the president cannot lift a beach chair which "weighs nine ounces").

One thing missing? Any mention of Haley. Remember, Trump is not technically the nominee until the convention says so, and he's not the presumptive nominee until he wins enough delegates. He is having a super Super Tuesday tonight, but he's not quite there ... yet.

Dean Phillips's tepid campaign may not last until the morning. Phillips has previously stated that he would drop out and endorse the likely Democratic nominee if his campaign wasn't viable after Super Tuesday. So far, his highest level of support tonight is in Oklahoma, where he's currently pulling 9 percent of the Democratic primary vote. That's closely followed by his home state of Minnesota, where he's winning a similar level of support. But at least he can say he won something today: tiny Cimarron County in the Oklahoma panhandle, where he currently leads Biden by five votes out of 21 total that were cast.

Trump is winning Massachusetts 61 percent to 36 percent, but as you can see in the map below, Haley is winning Boston and many of its well-to-do western suburbs like Concord, Wellesley and Weston. While these towns are now solidly Democratic, they are also home to a lot of the fiscally conservative, socially liberal voters who have supported moderate Republicans for governor like Mitt Romney and Charlie Baker. It’s basically the exact kind of well-educated voter that hates Trump but misses the old Republican Party, which Haley has become an avatar for.

Catching up on some ABC News race projections that we missed earlier:

- In the Republican primary for North Carolina's 13th District, ABC News projects that Kelly Daughtry and Brad Knott will advance to a May 14 runoff. This is currently a Democratic-held seat, but the GOP legislature redrew it to be safely Republican, so whoever wins the runoff should be a shoo-in in November.

- In the Republican primary for Texas's 12th District, ABC News projects that Craig Goldman and John O'Shea will advance to a May 28 runoff. This is a solidly red open seat currently represented by retiring Rep. Kay Granger.

- And a bit of a surprise in the Republican primary for Texas's 23rd District: incumbent Rep. Tony Gonzales garnered just 45 percent of the vote, forcing him into a runoff with second-place finisher Brandon Herrera. Gonzales was censured by the Texas GOP last year for supporting bipartisan gun legislation in the wake of the shooting in Uvalde, which is in his district. Clearly, the GOP base is still not happy with him.
