Wesley Clark`s campaign manager has quit. Donnie Fowler left the retired Army general`s campaign Tuesday after a disagreement over how Clark`s presidential campaign was being run. Fowler says he`s worried that supporters who used the Internet to draft Clark into the race are not being taken seriously by top campaign officials. Fowler also complained that the campaign`s message and methods are focused too much on Washington. Two associates of Fowler`s say he is concerned that the campaign is not putting enough focus on key states. National polls put Clark near the top of the nine-person field and he raised more than three million dollars in the first two weeks of his campaign.
