The New York Times looks inside the office space of the Obama fundraising machine and how his team is using the Internet to change the money game.

Mr. Obama’s finance director, Julianna Smoot, who has helped him raise more than $150 million so far, does not even have her own office. A Ping-Pong table is the gathering spot for Friday lunches for her team.

The setting, which has the feel of an Internet start-up, is emblematic of how Mr. Obama, of Illinois, has been able to raise so much money. On Wednesday, the Obama campaign will report to the Federal Election Commission that it collected $36 million in January — $4 million more than campaign officials had previously estimated — an unprecedented feat for a single month in American politics that was powered overwhelmingly by small online donations. That dwarfed the $13.5 million in January that Senator Hillary Rodham Clinton of New York is expected to report Wednesday and the $12 million Senator John McCain’s campaign said he brought in for the month.
