They can't survive free and fair elections

I used to think that. Trump changed my mind. He normalized behavior that has always been there, but people were too ashamed to show it in public. Now they wear their ignorance and prejudice like badges of honor. Yes, he lost the popular vote (both times). He also was responsible for the largest voter turn-outs ever (both times). His supporters are still winning in many areas. Expect Manchin to be replaced by a Rep, for example. Very possibly a Trumpie.

Nationally, without gerrymandering, I suspect the Dems would be the majority. But on the state level, Reps would control a lot of government(s). I've had to mark ballots in which there was no Dem running for a given office. Sometimes two (or more) Reps, no Dem. It's not a result of unfairness. The Dem just doesn't even bother because they have no chance in that region.
