It takes money to keep going
AP reports, in Money Crunch Threatens Some Democrats:
Gephardt's departure from the race should be a warning to the remaining candidates, including fund-raising leader Dean, said Tony Coelho, chairman of Democrat Al Gore's 2000 presidential campaign.
"He can afford to ride it out as long as he starts cutting costs," Coelho said. "He has extensive operations throughout a network of states, so the cost of his campaign is the most costly of all of them."
Dean raised roughly $40 million last year, nearly twice as much as anyone else in the Democratic race. Despite his third-place Iowa showing, by Friday afternoon, Dean had raised at least $750,000 of the $1 million he asked donors to give before New Hampshire's first-in-the-nation primary Tuesday.
Kerry and Edwards have also seen hundreds of thousands of dollars come in this week.
Like Dean, Iowa winner Kerry is trying to raise $1 million this week. The campaign had collected at least $860,000 over the Internet by Friday afternoon. Edwards raised at least $560,000 online since Monday night.
