So I just read two stories back to back: this L.A. Times story about the paper's new poll (also summarized at Polling Report and analyzed here), which shows Bush ahead of Kerry for the first time, and this story about Swift boat lead attack dog John O'Neill, who's been saying that Kerry couldn't have been in Cambodia after having told Richard Nixon (on tape) that he himself was in Cambodia.

Look, I'll say it again: It's time to do an ad putting the liars' words and the refutations back to back. It would be direct and it would be very effective. Why hasn't it happened?
