Obama also criticized opponent Hillary Clinton in the same sentence, seeming to imply that Clinton and McCain share similar positions on a variety of issues.
"It is time for new leadership that understands that the way to win a debate with John McCain or any Republican who is nominated is not by nominating someone who agreed with him on voting for the war in Iraq," Obama said, taking a swipe at Clinton's 2002 vote in favor of the Iraq war resolution.
McCain, fresh off his win in Florida Tuesday, is now being billed as the GOP frontrunner.
Obama continued the attack on Clinton, implying she also agreed with McCain when it came to giving George Bush "the benefit of the doubt on Iran," and criticizing her for "embracing the Bush-Cheney policy of not talking to leaders we don’t like."
The Illinois senator implied that he "actually differed with McCain by arguing for exceptions for torture before changing positions when the politics of the moment changed."
The Clinton campaign was quick to respond — so quick, in fact, that spokesman Phil Singer emailed a rebuttal to reporters before Obama had even delivered the comments.
Responding to what the Obama campaign sent out as remarks "prepared for delivery," Singer wrote that, with a single exception, the promotion of Gen. George Casey - the two senators have nearly-identical voting records on Iraq.
He also added that Obama is misrepresenting Clinton's position when it comes to the issues of Iran and diplomacy.
In terms of torture, Singer wrote that Obama "couldn't be more wrong." After meeting with various military officials and reading defense reports, he said, Clinton "concluded that torture cannot be part of the American policy, period."
