According to a new Philadelphia Daily News/CN8 Keystone poll, Sen. Rick Santorum's (R-PA) job-approval ratings are at a six-year low and he's trailing Bob Casey (D) in the U.S. Senate race, by 16 points, 51% to 35%.
The poll also showed Gov. Ed Rendell (D) with the lowest favorability rating since he took office.
Says the poll director: "We have a full-scale populist revolt under way."
