But he also says it stupid like them, in a way that can’t be faked. That’s why they love him. It’s the classic “wanting to hear your opinion in someone else’s voice”. They want to hear their shitty opinions in someone else’s voice. Except because they’re idiots, they get grammar and syntax wrong. Or they ramble through a dozen conspiracy theories in a single run on sentence. No one but trump can carry on the way he does (at least without a script).
