Reps. Mike McIntyre (D-N.C.) and Carolyn McCarthy (D-N.Y.) plan to retire rather than run for reelection, Democrats said Wednesday.

McIntyre's decision is a boon to Republicans, who have a close eye on picking up his seat. Mitt Romney won the district with 59 percent of the vote in 2012 and McIntyre won by a slim margin in the closest U.S. House contest of 2012. The GOP is now well-positioned to win the district.
