Nate Silver has some interesting stats on how education level was potentially THE determining factor in which way people voted.  An interesting sidelight to this, not mentioned in the article, is that whites with college degrees who have consistently voted Republican dating back at least to Reagan's 1980 run, broke for Clinton this time.  Meanwhile minorities and immigrants voted more heavily for Trump than they did for Romney or McCain.  I've yet to find clear data on the education levels of those who jumped to the Republicans, but Silver's data indicates that college or the lack thereof likely played a role.

It appears by this breakdown that the divide is increasingly one not of economic class, but of schooling.  This in turn is upsetting the established party coalitions.
