If it doesn't work....?

Over the weekend I asked, "What if the Republicans shout terrorist, and no one cares?"

Looking back, that's actually a pretty big narrative question. What if the McCain campaign spends three to five days on these "last ditch" attacks and the polls don't appreciably move?

Isn't the narrative then that the race is over?

(Can you really imagine McCain picking up ground in the economically sensitive battleground states right now?)
