By contrast to the evidence below, polls on Senatorial popularity are almost mind-numbingly positive. Only 3 Senators have a net negative popularity rating: Rick Santorum (-14); Conrad Burns (-13); Jim Bunning (-1). Only 11 Senators have net positive popularity ratings of 5 or under: Jon Kyl (3); Wayne Allard (1); Mel Martinez (0); Debbie Stabenow (2); Mark Dayton (2); Jim Talent (5); Frank Lautenberg (0); Robert Menendez (0); Richard Burr (2); George Voinovich (2); John Cornyn (3). Of those 14 Senators, 10 are Republican. A lot of these are in swing states, but that doesn’t explain everything–especial John Cornyn’s especially unimpressive ratings.
