She cheats, but more seriously, she has a campaign apparatus (including loophole organizations to work around McCain-Feingold) with very deep pockets, support from the none-too-entertaining entertainment industry, and of course, partisan media shills. Even Howard Dean's DNC chairmanship works in her favor, because when he is replaced (by Hillary, or resigns and is replaced by someone she favors), everyone in the Dhimmicrat apparatus will breathe a sigh of relief. After all, the radical minority which powers Code Pink, ANSWER, and other b...s... thug groups will spend the foreseeable future protesting against the other party.
