Mark Twain once said: "A lie can travel halfway around the world while the truth is putting on its shoes."
Bob McDonnell's campaign for the governor's mansion operates according to a variation on this theme. "We can lie about Bob McDonnell's record and the mainstream media won't catch up until two weeks after the election." McDonnell is counting on a certain amount of lag time between the election and when Virginia voters realize they've been lied to.
Waldo Jaquith accurately describes this strategy in his post about "Making Shit Up™."
This year's election really comes down to this: will the mainstream media continue to carry water for McDonnell, or will it begin to critically examine McDonnell's claims about his own record?
