I have a shit, /pol/ tier personal theory that JD Vance only exists in Trump's orbit because of Peter Thiel. (The closest thing to a George Soros of the right wing political sphere) Dude's got like... 9 Billion dollars and fucks around regularly with the GOP political world as a hobby. He's funded several far right, young politicians in the last few years that haven't really taken off. Madison Cawthorn being one of them.
In this shit theory, Peter made a demand that he would only continue the financial and political support of the shit show that is the GOP if Trump picked someone relatively young and unblemished to shadow and emulate him for his final years in politics to learn how to grift. But this time under Peter's venture capitol watch.
Peter's got a whole law named after him in the entrepreneurial world. "A startup messed up at it's foundation cannot be fixed". Trump is a lucrative, political marketing machine. But it's messed up and always has been. There's no fixing him and there's no fixing the political business he's created.
But take a fresh face and keep him in line while using some of Trump's political tactics? You might have something there.
... again. This is about the closest thing I have to a /pol/ tard boogieman theory in politics other than "The whole fucking thing is a shitshow and no one deserves a pedestal of worship in it. Ever."
