WASHINGTON — Barack Obama raised more than $150 million in September, a stunning and unprecedented eruption of political giving that has given him a wide spending advantage over rival John McCain.
The Democrat’s campaign released the figure Sunday, one day before it must file a detailed report of its monthly finances with the Federal Election Commission.
Obama’s money is fueling a vast campaign operation in an expanding field of competitive states. It also has underwritten a wave of both national and targeted video advertising unseen before in a presidential contest.
Campaign manager David Plouffe, in an e-mail to supporters Sunday morning, said the campaign had added 632,000 new donors in September for a total of 3.1 million contributors to the campaign. He said the average donation was $86.
The Democratic National Committee, moments later, announced that it raised $49.9 million and had $27.5 million in the bank at the start of October. The party has been raising money through joint fundraising events with Obama and can use the money to assist his candidacy.
Obama’s numbers are possible because he opted out of the public financing system for the fall campaign. McCain, the Republican nominee, chose to participate in the system, which limits him to $84 million for the September-October stretch before the election.
