Butterfield is a former state Supreme Court justice from Wilson who succeeded fellow Democrat Frank Ballance in 2004 in the predominantly Democratic district. Butterfield serves on the powerful House Armed Services Committee.
He was an adviser to Barack Obama during the 2008 presidential race and has been one of the president's staunchest supporters.
Woolard is from Beaufort County and is a vice president at his family's insurance company.
