FARMINGTON HILLS, Mich. (AP) — Barack Obama is putting as much heat on Sarah Palin as he is on the man at the top of the GOP ticket, objecting to the Republican Party's portrayal of her as a reformer who can bring change to Washington.

Obama said last week's Republican National Convention did a good job of highlighting Palin's biography — "Mother, governor, moose shooter. That's cool," he said. But he said Palin really is just another Republican politician, one who is stretching the truth about her record.

"When John McCain gets up there with Sarah Palin and says, 'We're for change,' ... what are they talking about?" Obama said Monday, arguing that they aren't offering different ideas from President Bush and they are just trying to steal his campaign theme because it seemed to be working.

"It was just like a month ago they were all saying, 'Oh, it's experience, experience, experience.' Then they chose Palin and they started talking about change, change, change," he said.

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.
