Sen. Barack Obama's campaign leaked its fundraising numbers to the Chicago Tribune this afternoon.

Bottom line: $55 million. That's $20 million more than Clinton raised. In one month.

Here's the Trib story:

Sen. Barack Obama raised $55 million in February, a stunning total that his campaign hopes will breathe fresh momentum into his presidential bid following losses in three of four nominating contests earlier this week.

The Tribune has learned the Illinois Democrat raised the amount in an effort that shatters the record for money raised by a presidential campaign in a single month.

The total came from contributions from nearly three-quarters of a million donors, including about 385,000 who were donating for the first time. Virtually all of the money - $45 million - was raised online.
