2014
Mitch McConnell- lots of people are laughing at this but I'm serious.
I'm not laughing. Never was.
Anyway, here would be my list. This doesn't necessarily take into account how these states voted in 2012, and we don't even know who's running in some of these races (colors are for the party currently holding the office):

WisconsinConclusion: 2014 could be a good year for Republicans in the Senate but for either party for Governors; 2016 should be good for Democrats for Senate and Republicans for Governors; 2018 should be good for Republicans for Senate.
