Sen. Olympia Snowe (R-Maine) may have the support of Maine's Tea Party-backed governor in her reelection bid, but she could still be in for a tough primary battle next year. New numbers from Democratic-leaning Public Policy Polling (PPP) show 58 percent of Maine Republicans prefer a generic "more conservative" alternative to Snowe in 2012. And just 33 percent of Maine Republicans said they will support her. According to the poll, 58 percent of Republicans in the state think Snowe is too liberal, while another 33 percent don't even think she belongs in the GOP, saying she should be a Democrat.
