Beyond “whomever holds the highest office at the moment,” there’s “whomever gets the biggest media coverage.” That might be Gavin Newsom, who’s not very popular, even in his home state. Bernie Sanders and AOC always get good coverage, but that’s partly because they’re so far outside the mainstream.
