Bloomer take #1: People who want to vote 3rd party and hate Florida Man (which Ronny D epitomizes)?
Bloomer take #2:
A person who votes for a Democrat named “Trump” in 2024.
Clinical psychologists and lesbians for the White House! Mary Trump 2024 LESSGO
Otherwise...
I'm beginning to think a lot of longstanding Professional Liberals, especially in entertainment and journalism (and regardless of how you understand what Michael Moore does for a living, he's definitely in at least one of those two fields), perversely want Trump to win again because it'll confirm their poor opinions of the American public. The NYT with its weird exoticization of Trump voters (almost to the point of an ethnic fetish for working-class whites) is especially bad about this.
A #NeverTrumper who believes that he's been "reformed", or perhaps a wealthy person who doesn't like Biden's economics. I don't think there will be that many Latinos who fit this category, since those who are afraid of "socialism" already swung massively to Trump, and those who were unhappy with the protests in the summer also mostly voted for Trump. It is reasonable to expect most Clinton/Trump Latino voters to keep voting Republican, though that's at least somewhat up for debate.
