Centrists

Only shocking if you haven't been paying attention:

The [left-leaning group Americans for Democratic Action] on Tuesday unveiled a 65 percent rating for both Snowe and Collins. That's a 15-point drop for Snowe, who earned an 80 percent rating in 2008. Collins, who earned a 75 percent rating in 2008, dropped 10 points.

Conservatives, meanwhile, have boosted their assessment of the Maine senators.

The American Conservative Union raised Snowe’s rating by 36 points between 2008 and 2009. Collins's conservative rating surged by 28 points after Obama took office.

Remember when, during the 2008 campaign, Collins told Mainers she would let Sen. Richard Shelby (R-AL) decide which way she should vote on key issues?

Me neither.
