Obama aides also said the moves by Bush complicate matters for McCain, who is more hawkish than his opponent on issues including the crisis in Georgia and the war in Iraq.

“What we have here, in many ways, is that a McCain presidency would look a lot like a Bush first term and a move back in that direction,” said Rand Beers, who served as a National Security Council staffer in Republican and Democratic administrations and is now an unpaid adviser to the Obama campaign. “The flip side of that is that John McCain is therefore to the right of George Bush, which I don’t think is the way he conceived of his campaign.”

But Randy Scheunemann, McCain’s top foreign policy adviser, accused the Obama campaign of “rank hypocrisy” and said it was “comical” for the Democrat to now claim accord with the Bush administration on some issues.
