Republican Dan Bongino, the former Secret Service agent running in Maryland's 6th Congressional District, raised more than $530,000 since July, significantly exceeding his past fundraising and nearly matching the incumbent's haul, campaign finance reports filed with the Federal Election Commission show.

Bongino is running an uphill campaign against Democratic Rep. John Delaney, a first-term lawmaker who beat incumbent Republican Roscoe G. Bartlett in 2012 after the state's 2011 redistricting.


Delaney raised just more than $591,000 over the same period.

The Bongino campaign noted it had brought in more than any of the state's House incumbents, including Rep. Steny Hoyer, the House Minority Whip and a prolific fundraiser. While the fundraising would pose a threat in many congressional districts, the impact in the Sixth will likely be blunted by the fact that Delaney, a former banker, has demonstrated a willingness to augment his campaign funds with his own cash.

The congressman spent $2.3 million of his own money on the 2012 election.

So far this cycle, Delaney has spent $77,911 of his own money and loaned his campaign another $160,000.

Another factor working in Delaney's favor: He has more than double Bongino's cash on hand, $450,000 compared with $169,000.

Bongino, an aggressive campaigner, ran an unsuccessful campaign for Senate in 2012. He published an autobiography last year and appears frequently on conservative media outlets.

But the new 6th district -- in which Delaney beat Bartlett by more than 20 percentage points in 2012 -- poses a challenge for any Republican. The contest has received little attention from outside conservative groups eager to expand the House Republican majority next year.
