FARMINGTON HILLS, Mich. (AP) âÄî Listening to Barack Obama, it can seem like Republican vice presidential nominee Sarah Palin is the main person standing between him and the White House instead of John McCain. Obama is putting as much heat on 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. That is supposed to be Obama’s distinction, and he’s not taking kindly to Palin trying to claim it. Especially when it appears the new star on the GOP ticket is helping to boost its standing: McCain has jumped to a dead heat or narrow lead over Obama in the latest national polls since choosing Palin as his running mate. Obama said last week’s Republican National Convention did a good job of highlighting Palin’s biography âÄî “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.
