Perhaps you‘ve seen it, the near-precise moment when John McCain lost control of his campaign. The scene is a now familiar one, the bogus “town-hall meeting.” He’s passing the microphone around like a decrepit Donahue, standing before a woman who starts by saying she “can't trust" Obama; McCain is nodding along, intimately engaged for the moment in manipulating the neurotic angst that is the dwindling lifeblood of his campaign. About the time she says her fear is due to what she’s been reading, a look of worry creases his trademark frown of condescending concern; he’s contemplating preemptively snatching the microphone back from her, when she lays it on him: Obama is “an Arab”. She's managed to confuse her slander (assuming there isn‘t an “Obama is an Arab” email careening about the internet), but it matters not.
