Facing a re-election campaign in 2010, Sen. Richard Burr's (R-N.C.) approval rating has dropped to 35%, with 32% disapproving and 33% not sure, according to a new PPP survey (March 12-15, 1000 RV, MoE +/- 3.1%).

The polling firm notes that Burr's numbers are worse than former Sen. Elizabeth Dole's (R-N.C.) at this point in her re-election campaign two years ago. Dole went on to lose to Democrat Kay Hagan by 9 points.

These poor numbers come as Democrats search for a candidate to challenge Burr. In this poll, PPP tested Sec. of State Elaine Marshall (D), who finished third in the 2002 Senate Democratic primary. Despite holding statewide office for years, more than 50% of respondents said they had no opinion of her.
