I just don’t think that’s a very big demo. Anybody who’d suddenly motivated to keep the White House white and estrogen-free are, more than likely, already foaming-at-the-mouth MAGAts who were 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.
