Oh look, more evidence that it’s isn’t both sides after all!
From the VoteView blog piece Polarization is Real (and Asymmetric):
[W]e should be careful not to equate the two parties’ roles in contemporary political polarization: the data are clear that this is a Republican-led phenomenon where very conservative Republicans have replaced moderate Republicans and Southern Democrats. Thomas Mann and Norm Ornstein do an excellent job of navigating these trends in their new book: It’s Even Worse Than It Looks: How the American Constitutional System Collided With the New Politics of Extremism.
The GOPs ongoing lurch to the right drags them further and further from mainstream America and from reality itself. But they have a bubble, so I’m sure they’ll be safe.
