Senate NORTH CAROLINA
INCUMBENT: KAY HAGAN (D)
First-term Sen. Kay Hagan won this swing state in 2008, running on the same ticket as President Obama. She also had the advantage then of running against Elizabeth Dole, a weak incumbent. In 2012, North Carolina went for Mitt Romney. For months, Hagan has been taking hits for supporting the health care law. On the Republican side, there is a crowded field with candidates taking their shots at state House Speaker Thom Tillis, the best-known GOP contender.
