Kamala should just have mock debates at every one of her appearances, with a Trump impersonator in a chicken suit. The impersonator doesn't even need to say anything, they can just play actual clips from Trump rallies of Trump saying stupid shit for her to respond to. He'll cave within a week, and his acolytes will insist this was his plan all along.
I would love to see this. Trump can't stand being called a loser, it would be awesome for these mock debates to focus on tactics that drive narcissists crazy
