been that of areas assimilating more to how they should be voting. The link below is what I'm talking about. http://uselectionatlas.org/FORUM/index.php?topic=207702.0
The presence of a lot of "should be voting this way" areas have declined as they have generally assimilated to there counterparts nationwide. An example is areas like DuPage County, IL or Cottle, TX which are voting more or less how you would have expected them to all along. Also in Kentucky there was marked difference in areas like the old 5th and old 7th districts, both of which are converging politically.
If the dems go the Elizabeth Warren route then all bets are off but if the dems go more the Clinton route, places like Morris County, NJ I think should eventually assimilate to voting more like Nassau or Suffolk County, NY for example.
