I.e. which has the fewest voters.
I'm leaning towards something like Gore-Bush-McCain-Obama-Clinton-Trump. Bush vote implies pro war, but that fails to explain Trump in 2020. I don't think you'd get many people like that.
Somerset County, Maryland, was Gore-Bush-McCain-Obama-Trump-Trump, with a GOP swing from '16 to '20, so this is theoretically possible in certain quantities there although the county is racially polarized enough that differing turnout dynamics between elections probably explain more of it (especially McCain-Obama, given the behavior of similar counties such as Nash, NC, or Warren, MS). The very isolated and idiosyncratic community of Smith Island, however, is known for Haredi-type bloc voting in massive swings, which makes me wish I could find election results for there from before just what DRA has to see if there would be any basis to that.
