Ann Coulter already told us that Tea Partiers opposed to Mitt Romney were just a bunch of “birthers” (emphasis mine):

Pemmaraju pressed Coulter on Romney’s conservatism, adding that the Tea Party has resisted him strongly, an indication he may not be as conservative as she thinks. Coulter replied that the Tea Party was “wrong about this” because “they’re looking at who is going to go around bombastically demanding to see Obama’s birth certificate or calling him a Kenyan,” instead of substance.

So I can’t say I’m surprised to see one of the more active Romney supporters on Twitter assert this line of defense as to Romney’s refusal to release income tax returns:

Somehow I doubt playing the birther card will prevent Mitt Romney from having to release his income tax returns, or pay the consequences in a general election.
