Definitely agree with the former.
As for the latter, I think it's easy for both sides to say the other has become more radical. The loudest factions are at the fringes of both parties. I've tried to find some research on political movement from center, didn't turn up anything great.
In many ways, much of the right is a lot more centrist than they were in, say, the early 2000s. Certainly in the social sense. As for economics? I mean, I'm not even sure where to put populism on the left-right spectrum. There's definitely a lot more stupid in our modern politics. I think that's just true on average. Next to no critical thinking from basically anyone.
A lot of the right would use terms like the "
Overton window" to say that they haven't moved to the right, it's the spectrum that has moved to the left. I don't know that I totally buy that, but I do think it has some merits, at least on social issues. But then, as I said, I think a lot of folks are a lot more tolerant socially than they were before, so I'm not really sure how to square that all.
