AOC as the Democrat's candidate seems like a path to another Trump-type Republican in the White House. There must be few Democrats the Republicans would prefer to face in a national election.
It might not be inspiring, but for now I just want the Democrats to nominate moderate presidential candidates who will win. Even the worst Democrat is light years ahead of the best post-Trump Republican. There's too much at stake and the world literally might not survive the consequences of the next Trump or Trump-like presidency.
