I don’t think Joe has to pander to anyone like that. People who believe this stuff would never vote for Joe, anyway. They are too far gone—they probably have always been too far gone—and, fortunately, there are too few of them to make much of a difference, anyway. I think the only way they could ever come to make any difference is if a Trump-like character somehow took over the “Democrat” party, which is the fervent fever dream of the Bannonites.
I can’t even imagine who that might be—my best guess would be a yet-to-be-known white male version of AOC—but I’m sure someone in Moscow is working on that puzzle right now.
