I don’t think every Trump voter is a rabid racist, and macroeconomics do matter. They just don’t think the government, or the Democrats, or the other Republicans give a damn about them. They are alone and just want someone to tell them there’s someone to blame, and someone is going to make them pay for their suffering. Trump is their winner that champions them, or so they think, because no one else gives a shit about them. Does Biden convince them that the government really cares? Not a chance. Voting for Trump is exploiting the blind anger many people feel because of their powerlessness. If you want to win an election, you tap into that. People don’t really care what Trump says, they are desperate and angry and want to have someone pay for their suffering.
