A new Survey by Public Policy Polling shows that Pat Roberts is one of the most anonymous Senators in the country. 31% of voters approve of him, 28% disapprove, and 41% don’t have an opinion either way. The only Senator in the county Public Policy Polls found with a higher percentage of voters having no opinion about him is first termer Mark Kirk of Illinois.

Jerry Moran is Kansas’ more popular Senator with a 38% approval rating and 27% disapproving, although that makes him one of the less well-known Senators in the country as well.

Nevertheless Roberts shouldn’t be in too much trouble next year, at least in a general election. He leads every Democrat Public Policy Polling tested against him by double digits- it’s 11 points over Kathleen Sebelius at 51/40, 15 points over Mark Parkinson at 49/34, and 16 over Carl Brewer at 50/34.

Roberts’ low profile could give him more trouble in a primary. Just 42% of Republicans say they would vote to re-nominate him, while 34% say they would prefer someone ‘more conservative.’ Those are pretty uninspiring numbers if a more fiery candidate wanted to challenge him from the right. Roberts has bigger leads over specific GOP alternatives we tested against him though- 21 points over Todd Tiahrt at 47/26, 31 over Tim Huelskamp at 53/22, and 36 over Kris Kobach at 55/19.

Democrats might have a better chance with someone like Huelskamp as the GOP nominee- he leads the Brewer/Sebelius/Parkinson trio by only 4-6 points. But obviously the Republican lean of the state will make it hard for Democrats regardless of the GOP candidate.
