The exit polls were explicitly clear: those who voted had their minds made up well before the election and leaked emails had little effect on the voter's decisions. What little effect the leaked emails had amounted to nothing more than affirmation of a decision already made. 

I made a couple of fishing trips in the late summer and early fall. The sheer number of Trump signs along the rural routes were legion...you know... places Hillary stuck her nose up at and shunned....there's your election, folks. The election was not Trump's to win, rather, the election was Hillary's to lose. And lose she did.
