Democratic challenger John Delaney outraised longtime Republican Rep. Roscoe G. Bartlett by a 6-to-1 margin in the first half of October and had more cash on hand going into the final weeks of the campaign, according to figures released by the Federal Election Commission.

In the state's most competitive congressional race, Delaney raised more than $251,000 between Oct. 1 and Oct.17 — a period that included a Washington fundraiser headlined by former President Bill Clinton. Delaney, a Montgomery County banker, had $173,000 on hand.


"John is overwhelmed by the support he has received," said his campaign manager, Justin Schall. "John's message of job creation and putting country before party has generated an outpouring of support from across Maryland and around the country."

Bartlett, seeking an 11th term in a district that was redrawn last year to give Democrats a chance at a pickup, raised less than $40,000 during the same period. He had $110,000 on hand.

The Bartlett campaign did not respond to requests for comment.

The numbers are contained in the final round of campaign finance reports to be filed before the Nov. 6 election.

Delaney raised $3.75 million for the 2012 cycle, which included a competitive Democratic primary before the general election. Bartlett, who faced a competitive GOP primary, raised $1.12 million.

Among House candidates from Maryland, only Rep. Steny H. Hoyer, the No. 2 Democrat in the House of Representatives and one of its most prolific fundraisers, took in more than Delaney.

The $4 million raised by Hoyer during the 2012 cycle is more than 25 times the $146,000 raised by Republican challenger Anthony J. O'Donnell, the minority leader in the Maryland House of Delegates.

The rest of the state's incumbent House members also outraised their challengers.
