I think the next time Republicans win they will win fairly big. I am expecting Clinton to run and win in 2016 and I'm not sure there's much the GOP can do to stop that, except to pray that Obama falls toward 30% approval. But 2020 could easily be reverse 1992, with the Midwest giving out all at once like the Upper South did in 1992:
Why wouldn't the Republicans win NV or NM in this scenario? If they're winning OR, ME-AL and IL in this scenario, surely NV and NM would have fallen to the Republicans, barring a horrible performance with Latinos.
