Only one-third of North Carolina registered voters approve of Sen. Kay Hagan's job performance, her lowest rating in a year, according to the latest Elon University Poll. Hagan was the only politician in the poll whose job approval rating dropped since November. President Barack Obama, Gov. Pat McCrory and Sen. Richard Burr all achieved at least modest gains. Forty-nine percent of respondents said they disapproved of Hagan's job performance, her worst rating in a year.
