Some sober advice and encouragement for the president-elect.  Larry Arnn sets the tone most appropriately:

I think the key thing he has got right now is that the constituent element of the nation is the citizen. It is not the identity group. If there is to be any consistency or long-term representation of these citizens, they must be organized to produce “constitutional majorities.” It requires a form of government that is stable and well designed in order to amalgamate opinion and produce action. It turns out we have the best form ever invented for this, and Mr. Trump seems to understand that.
