The progressive wing of the democratic party now has more leverage within that party. Furthermore, http://www.nytimes.com/2016/11/13/business/economy/can-trump... does paint one of the nicest images of Trump voters, implying the Rust Belt voters who most dramatically swung republican vs 2012 and 2008 voted Trump in on a Sandernist mandate.
So 2020 could be interesting, but man waiting through 4 more years of gridlock will suck. If it weren't for supreme court I'd love to strike a bargin of "4 years your stuff, 4 years ours", so we'd actually run a good policy experiment.
