I do think the above image captures a truth. But I'm also not convinced that the forces driving politics from the Democratic side are all that much better. Anyway, I have a new thing up at Medium.com on political polarization and how it is worse now than ever, according to voting patterns in congress:
Political polarization and gridlock. It’s worse that ever, or at least it seems that way. In fact, it is worse than it has been for 65 years. That’s the conclusion of a recent study by researchers who looked at the history of political polarization in the US since 1949, as judged by congressional voting records. The study found that cooperation between members of different parties is now lacking more than ever before. Things were actually a lot better back in the Nixon era, even during the most divisive days of the Vietnam War and Watergate, when a President and Vice President were forced to resign, and even in the aftermath of the assassinations of Martin Luther King Jr. and Robert F. Kennedy.
The whole (short) thing is here.
