Ayman al Zawahiri is by no means a shoo-in as al Qaeda's next leader. He is not liked by many in the organization, and he faces competition from at least two others, one of them an American, a senior U.S. official tells NBC News.
In addition to having a face for radio, and not at all charismatic, he is not nearly as popular as bin Laden internally. He has a reputation as being arrogant," said the official. "We could see Anwar al-Awlaki move in, or Ilyas Kashmiri, a Pakistani militant.
Al-Awlaki, 40, is the New Mexico-born American leader of al Qaeda in the Arab Peninsula, who had contact with both Abdul Muttallab, the underwear bomber, and Col. Nidal Hassan, who killed 15 people at Ft. Hood two years ago...as well as two of the 9-11 bombers while preaching in San Diego.
