Very well could be, but I think this is more lib Politico trying to stir up trouble. Paul supporters are not going to vote for Obama, yet still may vote for Romney. It is in the Lib's interest to do everything they can to prevent Paul supporter from backing Romney.
Michigan has a large amount of Paul supporters and Rep. Justin Amash who still says he has only endorsed Ron Paul for prez, yet Michigan is dead center. Also, the article lists Iowa as one of the states in which Paul received a majority of delegates and yet they also have a good spot.
I, for one, am still hoping that Romney puts Paul in charge of the Fed. That would be a great day.
