This video, in which he gets asked about Romney's comments that he "doesn't have the same feelings about American exceptionalism that we do," isn't President Obama's finest hour:

Here's what he says, according to the Washington Examiner:

It's worth noting that I first arrived on the national stage with a speech at the Democratic convention was entirely about on American exceptionalsim, and that my entire career has been a testimony of American exceptionalism. But I will cut some folks some slack for now because they are still trying to win their nomination.

Right-wing blogs will hit the president—and fairly so, I think—for answering a question about American exceptionalism entirely using himself as an example. Granted, a joint press conference between the leaders of the U.S., Mexico, and Canada maybe isn't the best place to extol the glories of Americans above all others, but the misquote on the title of this video, "Obama to Romney: I am American exceptionalism," is going to haunt President Obama all the way through the election. His dismissal of Romney as "trying to win" his "nomination," though, is spot-on, a perfect example of the casual condescension that the incumbency gives to a president running for a second term.

President Obama's claim in the same press conference that the Supreme Court would basically be a bunch of activist judges if they overturn his health care reform law, too, is pretty sharp partisan politicking.
