Will the nominee come from who raises the most money or who has the best campaign. CNN WASHINGTON (CNN) -- Sen. Barack Obama's presidential campaign announced Wednesday that it raised at least $25 million in the first quarter of 2007. The total comes close to the $26 million raised by Sen. Hillary Rodham Clinton's campaign in the same time period and calls into question the New York Democrat's status as her party's front-runner in 2008. The Obama for America campaign said more than 100,000 individual donors had contributed to the 2008 presidential campaign of the senator from Illinois. "This overwhelming response, in only a few short weeks, shows the hunger for a different kind of politics in this country and a belief at the grass-roots level that Barack Obama can bring out the best in America to solve our problems," said Penny Pritzker, Obama for America's finance chair, in a news release. Since Obama announced his presidential bid on February 10, his campaign has raised $6.9 million over the Internet from more than 50,000 donors, it said. The online fundraising is included in the $25 million total. Dan Balz, political correspondent for The Washington Post, said: "I think the challenge for him is to figure out how to bottle up this enthusiasm and turn it into something that can sustain him for a much longer period." The first quarter of the 2008 fundraising cycle is considered by many to be a reliable benchmark to assess a candidate's viability. The quarter closed at midnight Saturday. Clinton also transferred an additional $10 million from her Senate war chest to post $36 million in the first quarter. But Obama's fundraising prowess was the second blow in as many days to Clinton's aim to become the Democrats' "inevitable candidate." A poll released Tuesday indicated Clinton's once double-digit lead in the key primary state of New Hampshire has eroded since February, while rival John Edwards has made a run toward the head of the pack.
