No matter who is in power, they are all imperfect humans, & as such will do some stupid things, worse still, they will do self-serving things - to the disservice of everyone else. Hopefully, this time, the Reps will act honorably, pragmatically, use common sense, & be effective in returning our country to the Constitutional Republic it officially is. 
Yeah, I'd like to see bi-partisan cooperation & fraternity, but already the Muslim wannabe chair of the DNC is voicing how Dems can corrupt the process in their efforts to obstruct the Reps.
One of my greatest dreads is that Pres.Trump will be the subject of assassination attempts, coming from both the established Left and the established Right. 
I predict that Trump will keep his promises, build the Wall, do the other stuff & return our country to American Nationalism.  He will be vociferously opposed on practically all his efforts by the Left & many of the Right.
