What will Trump do to heal the polarization in the country?

Political polarizations basically at the worst it's ever been (I saw some really good video on the changing partisanship of Congress votes but I can't seem to find it right now...), so I'm interested in hearing what you all think Trump can do (has already done?) to unite the country, and how that fits in with his campaign promises which has been very polarizing in itself.

I feel like some people will blame the mainstream media for making this harder and so on, but I don't think you can ignore that does represents the actual opinion of a lot of the US (probably even the majority based on popular vote depending on how you feel about voter fraud). And of course, this is always a two way street, but Trump is the dude in the drivers seat.
