(CNN) -- Sen. Barack Obama has promised donors that he will recapture the White House for the Democrats this fall.
Sen. Barack Obama addresses a town hall-style meeting Sunday in Reno, Nevada.
1 of 2 "I will win. Don't worry about that," Obama, the presumptive Democratic presidential nominee, said during a Sunday night fundraiser in San Francisco, California.
Obama raised a whopping $7.8 million in a series of events Sunday in San Francisco, a key fundraiser for the Democrat said. The campaign would not confirm the total, but, if accurate, it would present the largest Obama fundraising day to date.
Obama told his donors that the money was needed to help break through the public's cynicism about politics.
"The fact of the matter is, at a certain point, when government has not been serving the people for this long, people get cynical. They tune out. And they start saying to themselves, a plague on both your houses," Obama said.
"They are willing to consume negative information more frequently than positive information, for good reason. They've seen how promises haven't been kept."
Obama also warned his donors that the upcoming campaign would turn negative.
