The American Spectator reports on theories that McCain is currently behind Guiliani's troubles:

    The leak of the 140-page brief prepared by advisers of former New York Mayor Rudolph Giuliani has been the talk of Washington for more than a week, and by late last week, consensus was that the document was leaked by sources with ties to the presidential campaign of Sen. John McCain.

    Giuliani's document was intended to give the former mayor and his senior supporters a broad overview of what would be required to mount a presidential campaign for the 2008 cycle. It is similar to documents prepared for other candidates, including former Massachusetts Gov. Mitt Romney, former Speaker Newt Gingrich, and Sen. Sam Brownback.

    Giuliani, who rates as highly as McCain on such issues as national security and homeland defense, but is more moderate on some social issues, is viewed as the major threat to McCain in the center/moderate Republican arena.


Still, the Spectator notes, the leak this early in the campaign will probably not have long last damage for Guiliani:

    "There was nothing in that document that just about everyone who know Rudy wasn't already aware of or talking about," says a Giuliani supporter. "Okay, it was embarrassing that it was lost and made public, but there is nothing here that should doom his candidacy."
