He went to a non union plant, paid non union members to hold pro union signs, and then talked shit about unions.

He knows his bases only policy is “passing off liberals” so why not simultaneously flank them from the left and right even if it’s objectively hypocritical.

He knows rhe left tryst to have a veneer of being pro union so he simultaneously says he’s more pro union than them while talking shit about unions.

He’d be the dumbest motherfucker on earth if it didn’t work but fortunately for him there’s millions of even dumber and more hateful fucks, and, more importantly, his opponents weren’t the democrats.
