The dude got 74 million votes in 2020. Anyone can isolate a subset of racists or rich assholes and pretend that's representative of the whole. But it's not. Americans are broke as shit. He also scooped the angry desperate rust belt and piss poor West Virginians.

Republicans are going to do their thing and race-bait and keep the rage machine going, but it'll fall on waaaaaaay fewer ears if people aren't so damn desperate and angry at the system already.
