Allies of Alaska Gov. Sarah Palin are now trying to throw McCain aide Nicolle Wallace under the proverbial bus, and as they do so those in McCain's circle are wary of the impact on Sen. John McCain, R-Ariz., himself.
Since becoming McCain's running mate, there have been a host of issues where Palin publicly challenged decisions made by McCain -- withdrawing from competition in Michigan, for instance, or for not attacking Sen. Barack Obama, D-Ill., for his longtime relationship with the controversial Rev. Jeremiah Wright.
But nothing has seemed so resonant as $150,000 in clothes purchased for Palin and her family by the Republican National Committee.
