This one? Or this one?
I'd go with the latter, if only because Gallup has, historically, always had a Republican bias (not as bad as Rasmussen's, but definitely there when compared to other national polls). And, besides, whether the GOP nominee is Romney or Gingrich, neither one is going to run an inside straight on all twelve "purple" states.
On the other hand, if South Carolina really is in play, the GOP may not be able to afford to concentrate on the "purple states." In any case, the current GOP strategy of betting everything on sweeping both ends of Pennsylvania Avenue is in serious trouble.
Especially if there's any fire behind this smoke. Let's hope so.
