And then there was one.

Rep. Allen West's (R-Fla.) concession in Florida's 18th District contest left one yet-to-be-determined House race between a Democrat and a Republican: North Carolina's 7th District, where on Tuesday morning Republican state Sen. David Rouzer called for a recount of the vote that showed him losing to Rep. Mike McIntyre (D). 

"Considering this is the closest Congressional race in the country and in light of the irregularity previously found in Bladen County, which significantly reduced the vote margin at that time, I have decided to request a mandatory recount of the votes cast in the 7th Congressional District as allowed by law,"  Rouzer said. "In a race this close, accidental human error could easily change the outcome. It is important to ensure that every legal vote cast is properly and accurately counted."

According to the state Board of Elections, McIntyre defeated Rouzer by 655 votes -- a margin that is within the threshold to allow for a recount next week the state, where Republicans have already picked up three House seats this cycle.

With just McIntyre's seat in doubt, the House stands at 234 Republicans and 200 Democrats. In Louisiana's 3rd District, Republican Reps. Charles Boustany and Jeff Landry will face off in a runoff next month that won't change the party balance in the House.
