Simple electoral college math. Clinton will more than likely get well over the 270 required. Possibly 400 plus.
The Senate will go to Dems because of the RNC's complete stupidity and lack of leadership. The absurd Trump Candidacy is an example of GOP's fragmentation.
No one lives in the fly over states. Thus they do not amass the same number of electoral college votes than the population centers.
Clinton will win by a pretty fair margin.

Sabato's take as of four days ago.
Clinton: 352 Trump: 173
Silver has Clinton at 337.8 with an 85.7% chance of winning. He has Trump at 199.4 with a 14.3% chance of winning.
