I'm quite excited about the idea that his defence sounds like it's going to be "no, it wasn't insurrection, it was totally justified because the election was stolen from me". That'll go down like a fart in a space suit.
But I suspect he could turn up, shout "WE WERE TRYING TO MURDER YOU ALL AND I'D DO IT AGAIN, DAMMIT!" and the chicken shit Republicans would still acquit him.
