Presidential contender Sen. Barack Obama raised at least $32.5 million in the second quarter of 2007, topping his first quarter effort by nearly $7 million, the Illinois Democrat's campaign announced Sunday. More than 154,000 donors contributed to Sen. Barack Obama's campaign in the second quarter, his aides said. The Obama campaign said the senator raised "at least" $31 million in the second quarter in primary money, and a total -- counting $1.5 million in general election funds -- of $32.5 million. The amount is believed to be the highest ever raised in a quarter by a Democratic candidate, and exceeded what rival Sen. Hillary Clinton's campaign predicted she would raise in the same period, CNN reported. In an e-mail posted on the campaign Web site, Obama campaign manager David Plouffe said the fundraising will allow Obama to compete fully funded in all February 5, 2008, contests in states like California and New York.
