Because he thought he was helping trump defend democracy.
You see all the wackadoodle trump peeps are hearing his dog whistles and going out and doing what they think he wants them to do. This is just the beginning folks. You know the trump won't stop. He will just double down and keep doing it. He and his peeps will insist none of the carnage is his fault. They will blame democrats for all of it and he will keep racisting from dawn to dusk every day. He would not have it any other way. The trump attracts all the weirdos. He likes them. He can relate to them. He has made them feel useful.
