Public Policy Polling just conducted a poll in which they tested how well Sen. Olympia Snowe (R-ME) would do in a GOP primary against an unnamed right-wing/conservative challenger. In other words, how well she'd stand up against a stiff Hoffmanization. I'd figured Snowe was pretty much invulnerable in Maine, even though Republican primary electorates can lean pretty far right. But not so. PPP had the winger candidate crushing Snowe by a 59% to 31% margin.

Not surprisingly, Snowe's approval among in-state Dems is far higher than among Republicans.
