Paul, the ugly truth is there are lot of American with undiagnosed mental illness. That's why people believe in abject BS like QAnon. And a QAnon nut could get elected to Congress! On top of that the right-wing media has spent close to 30 years pumping out misinformation to the point people can't even discern facts from conspiracy theory anymore.
Can you believe we still have flat Earthers and idiots who still believe Obama was born in Kenya? They want to debate the truth! There are people who still don't believe COVID-19 is real! Some of them have to learn the lesson the hard way by dying or getting infected!
That's why a sociopathic criminal like Trump could get reelected!
