"Interesting" perspective, hope it will post, from a NY Magazine (Jonathan Chait) email newsletter:

The Post-Liberals Are Theorizing

I don't have anything to add or argue, except that definitions of terms seem important to share but often missing.
(Someone please define "leftist" as applies to S.American dictator vs. what Fox refers to as "Dems" - the radical left, leftists, etc.)
What is the difference between "far left" and "far right"? Is it like the earth, where it is not flat (despite #GQP) but gets you to the other side or pole if you just keep traveling.

Anyway, I thought this is thoughtful...
