Obama Raises More Than $42 Million for Campaign

In addition to the money raised directly for his campaign, Mr. Obama helped the Democratic National Committee raise $27.3 million for a combined total of nearly $70 million during July, August and September.

Jim Messina, the campaign manager, announced in an e-mail to the president’s supporters that 606,207 people donated to BarackObama.com, including more than 250,000 who had never contributed to the president before. While the Republican candidates remain focused on the early primary and caucus states, the Obama campaign, Mr. Messina said, was using its early fund-raising to set up campaign offices and build a ground infrastructure for next year’s election.
