Ron Paul's inability to win a single state through this election season is now affecting his ability to raise money.

February fundraising figures show Paul raised about $3.3 million for the month, less than the $4.5 million in January and beginning March with $1.6 million on hand.

The Texas congressman's campaign filed the report with the Federal Election Commission tonight, four days before the March 20 deadline.

Paul had been a prolific fundraiser. By the end of January he had raised $31 million, placing his second to Mitt Romney among his GOP rivals.

The bulk of the money coming from small-dollar donations, according to the Center for Responsive Politics, a non-partisan, non-profit research group dedicated to tracking money in U.S. politics.

Paul's campaign does not have "bundlers," people assigned to raise large amounts of money for the campaign.

Politico reported earlier this month that Endorse Liberty, one of the large Super PAC's supporting Paul was reassessing its heavy financial support.

Endorse Liberty has tried to use online advertisements to broaden Paul's appeal. But the Super PAC too is running thin on available cash. Through January, it reported less than $61,000 on hand.
