I just don’t think that’s a very big demo. Anybody who’s suddenly motivated to keep the White House white and estrogen-free is more than likely a foaming-at-the-mouth MAGAt, who was already motivated to put their guy back in office. There will of course be a few people who fit that description, and probably many more diet racists and sexists who will just stay home if their options are Trump or a “left-coast liberal woman,” but I don’t think they make up a significant-enough proportion of the voting public to outweigh that latter group you mention, who couldn’t muster much enthusiasm for Biden but are amped-up to vote for somebody younger, healthier, and more dynamic.

Are there a lot of people who individually hold chaotic, mutually-incompatible political opinions? Sure! I don’t think you can boil their ultimate decision-making process down to a box-ticking exercise, where if a candidate represents sufficient number of demographics they hold bigoted views about they automatically vote for Default Old White Guy. For example –

I can’t even tell you how many people had both Bernie and Trump as their top two candidates in the 2016 and 2020 elections.

– that’s very clearly low-information voters dissatisfied with the status quo, who would happily glom onto anybody promising to sufficiently shake things up. Sure, Trump and Bernie had wildly-divergent platforms, but Joe Sixpack – who probably doesn’t feel like he has a dog in the fight on any of the particulars like abortion or finance law and assumes anybody sticking it to the broader political class is a net positive for him – doesn’t see much practical difference, and is so little affected by the bigotry of the right that none of it bothers him, so of course the two candidates presenting themselves as outsiders with a plan to shake up Washington are basically interchangeable.
