Trump, with a mandate, will have to start to deliver on a restoration of small town/middle/rural/working class America. Deportations will not be enough. The majority of Congressional Republicans, not to mention Democrats, are still "establishmentarians" that favor globalization, finance-centric corporatism and a consumption based economy. It will be interesting to see who becomes Senate Majority Leader, for instance.
As Matt has pointed out, the divide in the country is boiling down to a simple, classic clash between the classes. Very tenuous times still ahead.
