I’ve found the quote they misrepresent as Vance saying Trump was Hitler.
“I go back and forth between thinking Trump is a cynical asshole like Nixon who wouldn’t be that bad (and might even prove useful) or that he’s America’s Hitler. How’s that for discouraging?”
It was a personal message to a friend and shows that his comment is taken out of context and distorted.
Vance was asked about that quote. He said something like Yeah - its true. I had my questions about Trump. But seeing what he was like as president those questions were answered.
