IMHO, Primary Season is effectively over with NH now in the bag.
Haley's votes were largely Democrat crossovers who were trying to poison Trump's margin. Of course they'd never vote for her in the general election but New Hampshire has an open primary, so if there's no primary on the other side then the other party's people get to play games with yours without having to do any work up front (like change their registration.)
I've often been a part of debates on the entire "open/closed primary" thing, particularly when I was involved in the Libertarian Party, because it meant that to choose to vote in the primary meant you had to change your registration. In the general it doesn't matter of course since you only get to vote once. Then you have a situation like NH come up -- where the Democrats don't even bother with a primary, or as always happens someone is an incumbent and 90% of the time its irrelevant (e.g. Obama's or Bush's second term) and thus the "poison" game gets played.
Its events like this that lead me to conclude that while Florida's closed primary isn't a perfect thing it at least makes it a bit more-difficult to play this sort of game, and if there is any sort of real contest (remember, this is usually every other cycle if someone is an incumbent) to play it you have to remove yourself from your party's contest since you can only vote once.
Thus like it or not I've gotten rather warm to the idea that perhaps the closed primary is in fact a good thing rather than a bad one. A perfect answer, well no, because you could change your registration for primary season and then change it back, and that generally is easy enough -- never mind that it doesn't matter which party you are registered under when it comes to the general election, so if you forget to change it back -- you don't get disenfranchised.
Disentangling how many of those Haley votes really are Haley votes is somewhat difficult. You can look at so-called exit polls but they're not going to be other than a rough guess. What we can tell from the results is that it looks like about a third of Democrats, or maybe as many as half, did in fact play games because Biden won the state in 2020 and yet if you look at the Democrat .v. Republican vote in the primary you have roughly 102,000 votes cast (as I write this) on the GOP side and about 33,000 cast for Democrats. There should be about 70,000 Democrat votes assuming the vote splits as it did in 2020 which implies very strongly that of Haley's 47,000 effectively none of those votes are actual Republicans and in the general they would vote for Biden.
Yeah, that's more than a bit nuts.
The bottom line is that Haley has no path. Nobody wants her in New Hampshire that would actually vote for a Republican in November. There are a bunch of Biden voters who would like to see her be there in place of Trump, whether because they honestly think Biden can beat her or they simply hate Trump doesn't matter -- either is enough for them to cross the tape.
Haley may try to stick around until Super Tuesday, but I'd like to know who's going to keep funding it. These results make pretty clear what's going to happen, and there's really no way the math works for her since plenty of the states are closed primary and while some people will change registrations I wouldn't bet on enough of them doing to it materially alter the count.
It is what it is.
