A little odd to see Obama approvingly citing McCain adviser and neocon stalwart Robert Kagan in a new TV ad. The ad cites a Kagan column from last year, which tried to make the case, in a sometimes mocking and sarcastic way, that Obama's foreign policy really wasn't all that different from the neocons'. The ad is running in the Navy home port of Norfolk, VA, where defense spending is obviously a big issue.
