(CNN) - Rep. Ron Paul's Republican presidential campaign brought in over $5 million the past three months.
The third quarter number is up from the $4.5 million the congressman from Texas raised in the quarter lasting from April through June. Paul presidential campaign chairman Jesse Benton confirmed to CNN the new fundraising figure, which was first reported by the Wall Street Journal.
Friday is the final day for candidates to fundraise in the third quarter. Final figures must be reported to the Federal Election Commission by October 15.
The fundraising tallies that the campaigns report are important, because in this period, before voters actually start voting in primaries and caucuses, campaign cash figures–along with public opinion polls–are seen as a gauge or barometer of each candidate's popularity and his or her campaign's strength and outreach.
Paul only trailed former Massachusetts Gov. Mitt Romney in the second quarter. Romney raised over $18 million from April through June. Romney will report raising between $11 to $13 million for the third quarter, according to a source with knowledge of Romney's fundraising.
Paul's raised much of his money from so called "money bombs," one or two day rushes of small dollar donations.
Paul, who's making his third bid for the White House, has been spending the money he's raising. Unlike most of the other candidates in the hunt for the GOP presidential nomination, Paul has gone up four times this year with paid ad buys on broadcast and cable television.
