Public Policy Polling suggests Sen. Olympia Snowe (R-ME) "could have a pretty hard time getting nominated for another term in the Senate as a Republican."
"There are now more folks in her party who disapprove than approve of Snowe's job performance. 46% of GOP voters think she's doing a bad job to 40% who give her good marks."
Against a generic conservative primary challenger, Snowe would lose 59% to 31%.
