Politico asks John McCain about his newfound un-maverickness:

John McCain — who built his political persona and his 2008 presidential campaign around the claim that he’s a “maverick” — told Newsweek recently: “I never considered myself a maverick.” 
When POLITICO asked McCain about the contradiction at the Capitol this week, the Arizona Republican grew visibly irritated and snapped: “I’ve been called a thousand things. It’s absolutely ridiculous.”
He said 48 percent of the homeowners in his state are underwater on their mortgages. He said he’s always “done what’s best for my state and the nation.” Then he said it again, adding, “People can consider me whatever they want.” 
And then he darted into the Senate chamber without explaining himself further.
