Historian David Greenberg, over at Slate Magazine, argues that the media protected Obama:
  • Throughout the year, Obama was often spared the task of defending himself because others with prominent media platforms did it for him. As the campaign progressed, a whole slate of possible criticisms—including legitimate concerns about his record or his foreign-policy chops—were deemed, as if by cultural consensus, beyond the pale. Indeed, it's worth recalling that October's hyperbolic claims about McCain's negativity echo similar (and similarly unfounded) claims about Clinton's campaigning back in the spring. Does Obama somehow invite historically unprecedented negativity? Or are his enthusiasts just unusually quick to perceive it? In any event, Obama benefited more from labeling his rivals as uniquely sleazy than he suffered from whatever sleaziness they displayed.

Speaking of media protectiveness, notice that Greenberg saved his defense of McCain (and criticism of the press handling of Obama) for after the election?
