I think that might put a lot of pressure on them, if there is bipartisan support in their state for overturning Citizen's United like the momentum has been building, so if a bill comes to their desk passed by their legislatures, they'd be hard pressed to not sign it.

Given the governorships up for reelection in 2014, I would put the following states in the category of perhaps signing on to overturn Citizen's United (or perhaps after 2014 if their governor gets thrown out as a result of standing in the way of this). Those running against them should definitely be using this issue as a campaign issue. As the election gets closer and money spending churns up, this will be more and more of a visible issue too.

Washington
New Jersey

The rest of the states are pretty red, but there are a lot of Republican gubernatorial seats up for reelection in 2014, so who knows if perhaps some bipartisan push might help one of them shift too. Perhaps Idaho might join us here in the NW and not be surrounded by states that will have passed it since Montana's already on board. And North Dakota with its unique state bank might also be thinking differently in this area too. As the article notes, if we get close to this goal of 38 states, we might have enough to push congress to vote on it, if those in congress feel threatened by their inaction that would lead to the unprecedented state initiated constitutional amendment that might seem very possible then. Many of them might feel their jobs in jeopardy too if they chose to ignore the heavy state grass roots efforts then, even if they are Republicans.
