Atlas likes to push this idea that 2016 was a year that really favored the GOP, but I honestly think it slightly favored the Democrats. I think NeverTrumpers and partisan Democrats who want to throw Hillary under the bus by pushing the idea that any Republican would have definitely beat her. It's pathetic, but whatever.
Generic GOP loses to Generic D every time in Presidential races now. Maybe my perspective is skewed from living in NYC, but the Kasichs, Rubios, and Jebs of the world come off as plastic robotic designated losers to me.
Map at the minimum. 279 O'Malley -259 Jeb
Map if Jeb really screws up. 347 O'Malley - 191 Jeb
