Does The Bain Story Have A Shelf Life?

Scott Galupo doesn't see the story fading before November: 

[W]hat matters is that conservatives are still looking for any reason not to rally around Romney. And if the symbolic thrust of Romney's campaign—that he's a private-sector wizard and turnaround artist—fails to excite GOP primary voters now, what's that going to mean for him in November? For a solid week, Romney pitched himself as the very embodiment of free enterprise. The doyens of market fundamentalism, from Rush Limbaugh to the Club for Growth, cursed Gingrich for his apostasy. And yet, if Rasmussen's data is right, Republicans are still signaling that they're unmoved. And if they're unmoved, imagine how the rest of the electorate will react to Obama's tweaking of Romney's master-of-the-universe status. Indeed, recent Pew data from the week of Jan. 11-16 show Romney's favorability ratings having taken a dip among all voters.
