Obama support from Maine

How Maine's GOP Senators Are Key to Obama's Agenda - TIME: "But what makes Snowe and Collins more powerful now is that they, along with Specter, are nearly the last survivors of a once common species of moderate Northeastern Republican. As the GOP's center of gravity moves to the right, the Democratic majority has fewer and fewer potential crossovers to choose from. That gives each woman enormous leverage in a Senate Republican caucus whose leaders cannot afford any defections if they are to sustain a filibuster. Both sides know that the math on any close vote is likely to come down to Snowe and Collins."
