Polls aren't worth a steaming pile of dogsh-t. Traditionally, undecideds trend away from the incumbent, and the latest poll I saw had Undecideds at around 5% in MO and AZ. Just remember that in 1980 polling was close the week before election day, but over the weekend all undecideds broke for Reagan.
