Success hasn't gone to Howard Dean's head, despite the fundraising and political victories the Democratic Party chairman has collected in the past year. We hear that he still tries to get home to Vermont every weekend and still lives in a hotel near Democratic Party hq when in town. He likes to eat at his desk, where he sometimes tries to book his own flights around the country. "He knows all the connecting-flight schedules, he's traveled so much," says a friend. And he won't use a limo to get around town, instead keeping the number of a favorite cab drivera Mr. Singhhandy.
