Ron Paul's presidential campaign has raised more than $2.5 million in its latest "moneybomb" fundraiser and hopes to tack on another half a million before concluding the event, according to figures posted to the campaign website.

Paul has leaned on the events — in which grassroots donors on Paul's email list are encouraged to give generously over a quick period — to propel the Texas congressman to the third-largest haul in third-quarter fundraising. In this latest ask, Paul told supporters that he needed funds to break through a "media blackout" that was keeping him from being covered like other candidates.

“None of our hard work matters unless I can raise the resources to break through the media blackout and take my message of liberty straight to the voters,” Paul wrote.

A study by the Pew Research Center's Project for Excellence in Journalism showed the Texas congressman has received the least overall coverage of any candidate, despite regularly placing in the middle of the Republican pack in polls. Pew found that between May and October, Paul was featured as the "primary newsmaker in only 2 percent of all election stories."

Paul has repeatedly cited media bias as a reason why his campaign has not taken off while on the campaign trail, pointing often to a segment on Comedy Central's "The Daily Show" where host Jon Stewart mocks cable news hosts for neglecting to mention the candidate.

The $2.5 million take by Paul will make his "Black this Out" fundraiser his highest total of the cycle, surpassing a Constitution Day effort that netted $1.4 million in September and an ask on Paul's birthday in August that raised $1.8 million.
