Now, you can lead that way after the fact, but that's simply not how you win elections. You win elections in America by fighting, dirty if you have to; and that's probably especially important when the other guy is an actual fucking nazi who will lie his ass off, attack anything, anyone to rile up his base, and doesn't know or care what's out of bounds.
You're not gonna beat this guy because he goes too far. That's what he's about. You needa throw bows. Speaking purely tactically re: US history
