But the super PACs aside, there is also evidence that some of Romney’s Republican opponents may not be as willing as they were just a few days ago to continue their attacks.

The Note is hearing that Newt Gingrich’s attacks on Bain may be coming to an end. A GOP source says that Gingrich “got backlash from donors on Bain ads coming off as anti-capitalism.” Look for the former House Speaker’s team to pivot to other issues soon.

And Rick Perry, who accused companies like the one Romney ran of behaving like “vultures,” seems to be backing off too. As ABC’s Arlette Saenz notes, though Perry began his day by bashing Romney, at his last three events he completely wiped the rhetoric from his speeches.
