I've been keeping an eye on Wolfeboro, New Hampshire, where Romney owns a summer home. But so far, the community that gave Trump 30 percent of the vote in 2016 has yet to weigh in.

Trump's victory speech tonight struck me by how angry it was, especially after his attempt to be a little more conciliatory following Iowa. He wouldn't even mention Haley by name, calling her an imposter instead. He suggested her ally Sununu was on drugs, and brought on Ramaswamy to launch more invectives in her direction. If you're Haley, and you relish getting under Trump's skin in a way that few other candidates have managed so far, why are you going to drop out? Haley is wily and has delighted in running against those who have dismissed her for as long as she's been in politics, so I imagine speeches like Trump's tonight only fuel her.

Trump gave Ramaswamy 60 seconds on the mic, who used his time to suggest that Haley staying in the race is the "ugly underbelly of American politics." In political science we call that "exit talk," and according to research, women who run for the presidency have been subject to more "exit talk" than men.

In a rambling speech with his former challengers Sen. Tim Scott and Vivek Ramaswamy behind him, Trump criticized Haley for giving what he called a victory speech. "She failed badly," he said. He also had words for Gov. Chris Sununu, who'd endorsed her. He said that he would beat Biden and also claimed again, falsely, that he won in 2020. Ramaswamy took over the mic to praise Trump before Trump transitioned to immigration, repeating many of his false claims about open borders. In all, he was ready to dismiss Haley and pivot to the general election.

Big picture, this was a good night for Trump, who gets another win under his belt, avoids the embarrassment of losing an early state, and gets to compete in much more favorable territory from now on. It's obvious he's going to be the Republican nominee for president. But I don't think we should lose sight of the fact that just under half of Republican primary voters in the first two states voted for someone other than Trump, even as his inevitability has become apparent. I do think that should be a cause for some concern among Republicans moving forward, given that the general election will likely be brutally close and even a small drop in Republican support for Trump could prove fatal. The longer Haley stays in, the more data we'll get on just how many GOP voters there are who are not entirely on board with Trump, especially as she steps up her direct attacks on him. There's been so much conversation about Biden's struggles within the Democratic coalition — which are real and worthy of attention — but Trump may face similar challenges as the nominee as well.
