She should campaign for his primary opponent
Great idea. That could be the opening blows to get rid of liberals posing as conservatives going into 2012. McCain needs to be voted out of office for being an impostor, and the sweetest way would be an overwhelming conservative referendum by conservatives in his home state voting for a conservative in the state primary, publicly supported and campaigned by his former VP running mate that he allows his staff and fellow liberals to trash to this day. Same goes for his runnin' buddy Kyle when his time comes. Dump those two turds, Arizona.
