Romney won 39% of Hispanics in Florida in 2012. It's not tough to see Trump falling completely off a cliff to 25-30%, with Cubans voting for Hillary over Trump. Trump would also underperform with educated whites.
Of course, you have no difficulty seeing any fantastic result that benefits your party.
How about considering a TRUMP sweep of PA, OH and MI?
Republicans will need to win both Ohio and Pennsylvania should they lose Virginia. They will also need Iowa, Michigan and Wisconsin to win if they should lose Florida as well as Virginia.
Republicans can basically count out Michigan due to the toxic waters of Flint and Wisconsin, where the the Walker governorship is more metaphorically toxic.
Expect new polls to emerge from Ohio and Pennsylvania in a few weeks. The last ones date from when Hillary Clinton was reeling from the private server non-scandal and from Republican scrutiny of Benghazi. Then, and only then, can anyone speak of Republicans winning Ohio or Pennsylvania.
