All three stooges voted for the "Dream Act" and Porkulous, both of which are destructive to our country. Maybe she will stand up against the really destructive Supreme Court picks Present Obama will appoint and that would really be worth something, but can we count on her given what she's already done and what she's saying?
It sure sounds to me like Snowe is setting the stage for a switch (probably in return for being back in the majority and getting a chairmanship of a committee or something...). If she switches, don't expect one crumb of support for anything Republican.
I guess it comes down to whether or not you figure she's preparing for a big, dramatic triumph for Present Obama as He collects a defecting Republican which will also feature HER as a major DNC/media hero for months. I think she's going to. I could be wrong.
