An AP caption describes those pictured in this photo as "Supporters of Republican presidential candidate Sen. John McCain, R-Ariz., [who] are dressed as Joe the Plumber":

But CBS News reveals that one of the guys is a leader of the College Republicans, and although another is, in fact, a plumber, he's not even an American! So it turns out McCain supporters dressed up as Joe the Plumber are really McCain supporters ... dressed up as Joe the Plumber.

In other news, John McCain is not really a Georgian.
