Amb. Zalmay Khalilzad for Afghan president?

The Washington Post’s Al Kamen reports that U.S. ambassador to the United Nations Zalmay Khalilzad may be thinking of running for president of Afghanistan in the fall of 2009:

Honest. This is a real rumor. So real that we hear Afghan President Hamid Karzai asked Khalilzad about it when the two met in London back in October. But Khalilzad didn’t give a Shermanesque response.

Another U.N. official asked him to say no more definitively, but Khalilzad declined, another official told our colleague Colum Lynch.
