Indeed, some Sanders supporters have been blunt about their desire to gin up chatter about Biden’s mental state to derail him. In an episode of the popular leftist podcast Chapo Traphouse released Thursday, the hosts openly discussed how best to use the “senility” attack against the former vice president.

“I’m sorry, he’s senile… his brain is not all there,” Chapo co-host Will Menaker said.

Fellow co-host Amber A’Lee Frost urged Sanders supporters to use questions about Biden’s mental state selectively, raising questions about Biden’s support for Social Security when dealing with older voters instead.

“Now we go negative, but I think there’s going to have to be a two-front thing,” she said. “Because the ‘Biden is crackers’ thing isn’t going to work on his base, who are themselves also crackers.”
