(CNN) - In the final House race considered too close to call, Republican David Rouzer has asked for a recount in North Carolina's 7th Congressional District, where he trails the eight-term incumbent, Democratic Rep. Mike McIntyre, by a small margin.
"In a race this close, accidental human error could easily change the outcome," he said in a statement. "It is important to ensure that every legal vote cast is properly and accurately counted."

As of Tuesday, the website for North Carolina's Board of Elections showed McIntyre with 168,697 votes and Rouzer with 168,042–a razor thin margin of 655 votes or .2% of the total vote.
In his statement, Rouzer said he based his decision to request a recount on an "irregularity" reported in Bladen County.
Ray Britt, a Republican board member of the county's Board of Elections, said a technical problem with a cartridge in one precinct caused a set of votes to be counted twice. After the problem was fixed, he said, the board was able to double back and report the correct tabulation. After the correction, the results showed McIntyre had a lead but the margin had narrowed.
However, he said the county was ordered by the state Monday morning to do the recount along with all other counties.
"We have no problem with that because that's what you do" when the race is so close, Britt said.
Despite facing a newly-drawn district that appeared to have been created to end his career, McIntyre showed strong signs of life in the race and ran a competitive race in the district that skews heavily Republican. He led in fundraising over Rouzer, a state senator, and kept even with ad spending by pro-Republican outside groups and the national Republican Party. Rouzer, however, stayed off the airwaves.
Republican Rep. Allen West became the latest candidate to concede an unresolved House race when he announced Tuesday morning he would not seek further action after a recount revealed Democrat Patrick Murphy had a narrow lead over West in Florida's 18th Congressional District.
So far Democrats have made a net gain of seven seats in the U.S. House of Representatives. As of now, the new balance of power comes to 234 Republicans and 200 Democrats.
The GOP number includes a race in Louisiana that heads to a December 8 run-off election. However, the race is between two Republicans, guaranteeing a win for the GOP.
