They could, given how fluky governorships can be. I would bet against it, though. Arkansas is probably one of the last states to go Democratic.
Agreed. It's remarkable, though, that amidst of the 2010 Tea Party wave, Arkansas reelected a Democratic governor with 65% of the vote who swept every single county.
Almost no state shifted as fast as AR from Dem to GOP over recent years. Mark Pryor ran unopposed for reelection in 2008, Tom Cotton most likely will next year. At the national level, it even trended R from 2004 to 2008.
