Did Grampa legally change his name to John McCain, Maverick?

It's like some Jedi mind trick. I give him credit actually. No matter what he does, no matter how much of a blatant whore he becomes, no matter how much he compromises himself, he's still "John McCain, Maverick". Hey John McCain just literally kissed James Dobson's ass on national tv! Yes, he's a maverick, you know. Hey John McCain just kicked an old woman down a flight of stairs in a crazed fit of rage! He sure is a maverick isn't he? Hey John McCain now supports torture and tax cuts and Tom Tancredo! Wow, Ubermaverick! Seriously, if one journalist can go a whole McCain story without uttering that word, he should get a Pulitzer on the spot.
