Marginal REVOLUTION: Is America as polarized as you think?

The comments devolve in typically modern fashion. Look at the original posted study. We may be no more polarized than normal; it's simply weak study participation. Or ... it could be that science is fooling itself again (whichever way you parse it). 

In person, I see lots of angry people. Less talking, more stonewalling than normal. But even the hardest stone wall gets worn down. Say, by repeated mass shootings. The walls eventually 'come a-tumblin' down.'

[Sorry, I didn't intend italics. Squarespace lost its mind on that one. It's Friday night, and I'm too damned lazy to recreate it from scratch.]
