I was listening to NPR last night on the way home from a screening of Mr. Smith goes to Washington, and there was a discussion of the "hidden tribes" report that just came out from More in Common. The research indicated that policies are being driven by small minorities on the left and right - really small (8% on the left, 6% on the right) - that have outsize influence and do not represent the vast "exhausted majority" of the frustrated middle. Eye opening reading.
