JD Vance does what Peter Thiel tells him to do. And Peter Thiel is a fascist billionaire who ruined a company that outed him as gay. Thiel hates other people, especially women, which is why JD Vance says such weird things.
This feels like the Leftist version of a George Soros conspiracy. Why can the answer not be that JD Vance himself thinks the election was stolen? Maybe JD Vance himself is weird?
Well considering that George Soros conspiracy theories are usually based around using him as a boogeyman stand in for "the Jews" I think maybe your comparison is silly. Unless you really think the left needs one single Boogeyman for Christian influence on Politics. As if there wasn't thousands.
Someone else already said it, but Vance was picked for Trump, not by Trump. He was picked because he won't do want Mike Pence did in 2021. Vance is the best VP they could come up with that would go along with Trump's treason.
