The figure represents money raised both by the Obama campaign itself and the Democratic National Committee, and comes from 552,462 individuals, campaign manager Jim Messina said.
The contributions reflect "more grass roots support at this point in the process than any campaign in political history," Messina said, calling it a "monumental achievement." He said 98% of the donations were for $250 or less.
"You own this campaign, so you deserve to get this news first," Messina wrote. "And thanks to you and other supporters all over the country, there’s a lot of good news to share." - Campaign Manager Jim Messina
