From the AP:
Obama's campaign seemed to be caught off guard by McCain's surprise pick of Palin on Aug. 29. Obama's spokesman initially blasted her as a former small-town mayor with zero foreign policy experience who wants to continue Bush's policies. But Obama quickly walked the statement back with more congratulatory words about Palin as a compelling addition to the ticket.
Voters, particularly women, seem to agree, according to new polls. An ABC News-Washington Post survey showed white women have moved from backing Obama by 8 points to supporting McCain by 12 points, with majorities viewing Palin favorably and saying she boosts their faith in McCain's decisions.
