Clinton - 264
Kasich - 274
Wisconsin decides the Presidency -- and gives the Senate majority to Democrats.
(I see much the same result for Mitt Romney, and what I say of Kasich also holds for Romney).
Bare win... he would not have had the demagoguery necessary to win MI and PA, but more significantly he would not have had the coattails to protect the GOP majority in the Senate.
He would have to do outreach to Democrats with their Senate majority, and that would force a far-better Presidency than what Donald Trump has. At least we would not have a dictatorship!
...by the way -- Democrats would lose the Senate majority in 2018, and Kasich would likely get re-elected in 2020.
