How to explain such a disconnect?  By self-sorting within the electorate and the silo-ing of media consumption. That is, increasingly people live in homogenous communities with people who share similar likes, dislikes and, yes, political persuasions.  And, not surprisingly, the way in which they consume information, too, has become increasingly isolated/isolating.  Liberals watch Rachel Maddow, read liberal blogs and listen to liberal radio/podcasts. Conservatives listen to Rush Limbaugh, watch Fox News Channel and read conservative blogs. The twain never meet. They are ships passing in the political night.
