Abdullah Pulls Out?

Mac McCallister, a friend of Tom Ricks, thinks that Abdullah is just playing politics:

The Pashtun Karzai is still the front-man in this charade...In the meantime all will send delegates to Abdullah Abdullah to talk him off the ledge...The negotiations to keep Abdullah Abdullah in the game will be interpreted by all that Abdullah Abdullah has both credibility and legitimacy. In the end Abdullah Abdullah's faction will be offered a greater share of the spoils... Karzai will be President... and the government will continue to frustrate the hell out of us.
