Poll Tracker

Republican Sen. Richard Burr's (N.C.) vulnerability heading into 2010 can be seen in a new survey from the Democratic firm Public Policy Polling, which showed him with just a 35 percent job approval rating and a single point lead in a hypothetical matchup against a generic Democratic candidate.

Burr, who is shaping up to be the most vulnerable GOP incumbent in the country, led a generic Democrat 42 percent to 41 percent in a hypothetical matchup but he did slightly better against his actual Democratic opponents. He led Secretary of State Elaine Marshall (D) 42 percent to 37 percent, attorney Kenneth Lewis (D) 43 percent to 37 percent and former state Sen. Cal Cunningham (D) 45 percent to 36 percent.

The automated PPP survey of 593 North Carolina voters was in the field Dec. 11 to 13 and had a four point margin of error.

Burr's 35 percent job approval rating was only slightly lower than his Tar Heel State colleague, Sen. Kay Hagan (D), who had a 36 percent approval rating. A full 44 percent of voters disapprove of the job Hagan is doing in the Senate.
