While Republicans aren’t dropping dead at the same rate, they’re arguably clinging to power for longer than is dignified. If AOC beat him (which polls show is very plausible), it would be a massive shift for the future of the Democratic party. Indeed, the way things are going, it’s not even a given that there will be free and fair elections in 2028. We must coalesce around whoever is best placed to chart a way out of Trumpism. And AOC, for all her flaws, has the sort of fight that is needed.
