I'm going to say that Rubio wins back a lot of white collar whites who voted for Obama --- the Dubya/Obama voters with college degrees and solid income potential. In many ways, this keeps the Republicans focused on the Sunbelt, but also with big swings in Virginia, Colorado, and Minnesota. The trio of Wisconsin, Michigan, and Pennsylvania still vote Democrat, while Rubio wins much more sober victories in Iowa and Ohio, and loses Maine-2.
Basically, the Obama/Trump WWC voters still vote Democrat, while Rubio wins back Creative Class white voters and lots of Hispanics for the GOP. Outcome is a similar electoral vote margin that Trump enjoyed, just with different states and probably with the popular vote going the same way as the electoral vote. Would have interesting impact on how Democrats proceed to move forward.
