It's official: Every independent poll since the summer has shown longtime U.S. Rep. Paul Kanjorski (D-Nanticoke) as the rare Democrat on the path to defeat.

The latest poll comes from SurveyUSA on behalf of Roll Call (subscription only), and finds Kanjorski trailing Republican Hazleton Mayor Lou Barletta by 6 points, 51 percent to 45 percent.

Echoing other political forecasts, Roll Call says Kanjorski "could be the most vulnerable House Democrat in the country."

The results of the survey closely mirror other polling that has shown Kanjorski closing the gap on Barletta but still trailing. A Franklin & Marshall College poll last month had Barletta leading by 5 points in the 11th Congressional District.

Like in other surveys, Kanjorski is not performing as well as Democratic presidential nominee Barack Obama in the district. The Kanjorski campaign has long maintained that its candidate will win the most important poll: Election Day.

The automated poll of 622 likely voters was conducted Oct. 30 to Nov. 2, and had a margin of error of 4 percent.
