Obama continued to do well among small donors; 54 percent of the money donated to his campaign came in amounts of $200 or less.

Priorities USA Action, a political action committee supporting the president, also got a boost in large donations.

After raising 58,816 in January, it reported getting $2 million in February, including $1 million from comedian Bill Maher, after the president signaled to wealthy backers that they should support the committee. The super-PAC began this month with $2.8 million in the bank.

Jim Messina, Obama's campaign manager, said on Feb. 6 that White House and Cabinet officials would begin helping the super- PAC raise money to take on Republican groups which are amassing millions to oppose him.
