Which polls?
I saw the show. Wait for the transcript. I believe Luntz was saying that if Bush has a 3 point lead going into the election it covers all the voter registration, and cell phone owners not pollable theories, and battleground state dynamics.
Luntz says momentum is clearly with Bush, that he is 4 or so points ahead now...
That the best way to look at polls is to throw out the high, the low and average the remainder to get where the race really is.
