Few of these polls matter until 2008.
While I generally share your skepticism of polls so far out, I don't in this case. We already know that jockeying for the Presidency begins a long way out from 2008. The whispers among Dems have already started that "she can't win" because of her high negatives. We saw similar things with Janet Reno and Howard Dean, albeit both during shorter time spans. Will it be enough to torpedo her? I don't know. But I am by no means convinced Ms. Clinton will even be able to win her party's primary, much less get 270 electoral votes.

Only the exit polls are important damit. John Kerry
