As much as anything else, presidential campaigns are won and lost by the media narratives that rightly or wrongly come to define a candidate.  In the case of Repubican nominee John McCain, the seemingly unshakable narrative of the political "maverick" could not be further off the mark. At almost every turn, McCain in his eternal quest for the White House has reversed long-held positions, compromised core principles and swallowed his pride in order to curry favor with both the leading lights of the conservative movement and right-wing Republican primary voters.  The untold story of campaign 2008 is simply that of John McCain's transformation from maverick to prostitute.
