Secrets of the 2008 Campaign -- Newsweek
Newsweek has reporters in each campaign team. They get more access to see and hear than the rest of the press corps, on condition they do not reveal anything until after the election.
"The Clinton campaign blew through cash: fancy hotels like the Bellagio in Las Vegas and the Four Seasons everywhere; thousands of dollars on flowers and valet parking; and one memorable $100,000 grocery bill at a Des Moines supermarket. Hillary never spent a night in a motel in rural Iowa if she could possibly avoid it. She preferred to overnight in the Presidential Suite in the Des Moines Embassy Suites and to fly alone in private jets, without the press or staff."
