I don’t believe it. As a Dutchman, I see it all over Europe too. The classic working man parties started catering to white collar some time ago, and the blue collars don’t want to hear it anymore. Bernie would still be a democrat, just like Biden, Obama and the Clintons. People didn’t see change during their presidencies, and they don’t believe anymore that this time it’s going to be different. So you get to see the kind of people that we used to laugh at in the nineties ruling countries right now.
Trump seems to be senile already (the dancing town hall meeting comes to mind), so I think it’s more the question when Vance will take over, not if he will try.
