If Romney Wins
2013: Democrats Win VA Governorship and Christie loses to a 2nd tier candidate in a major upset(he will suffer more than most from an unpopular Romney)
2014: Democrats make house gains but the real massacre is in the states. Democrats pick up governorships in South Carolina, Michigan, Ohio(every statewide office), Arizona, Florida, Pennsylvania and in upsets hold Illinois and Arkansas.
A lot of the governors elected in 2010 will not be re-elected no matter who is in the White House.
Rick Scott, Tom Corbett, Nikki Haley, and John Kasich are probably going to lose in 2014 no matter what. Ironically, Scott Walker and Jan Brewer, the two most nationally controversial governors, are probably safe due to Tea Party support, unless Romney wins narrowly and quickly becomes unpopular (which is likely).
