Americans for Prosperity - a group founded (inter-shell) by the hard-right Koch brothers, and highly active in support of Tea Party activities - has released its list of approval and disdain of members of Congress.
Whatever your view, it can be considered indicative: You may consider an A or an F from these guys a badge of honor, but it does give you a realistic idea of who the new hard right really likes and really doesn't, and in relative terms. There are no low-graded Republicans, or high-graded Democrats.
Here's the Northwest results (from their results page):
A+ - Representative Raul Labrador, R-Idaho (the only Northwesterner with a "lifetime" A+, though the fact that he's in his first term helps some); Senator Mike Crapo, R-Idaho.
A - Senator Jim Risch, R-Idaho
B - Representative Doc Hastings, R-Washington; Representative Jaime Herrera Beutler, R-Washington; Representative Cathy McMorris Rodgers, R-Washington.
C - Representative Mike Simpson, R-Idaho; Representative Greg Walden, R-Oregon; Representative Dave Reichert, R-Washington.
D - Senator Jeff Merkley, D-Oregon; Senator Ron Wyden, D-Oregon; Senator Maria Cantwell, D-Washington; Senator Patty Murray, D-Washington; Representative Peter DeFazio, D-Oregon; Representative Kurt Schrader, D-Oregon; Representative Rick Larsen, D-Washington.
F - Representative Earl Blumenauer, D-Oregon; Representative Norm Dicks, D-Washington; Representative Jim McDermott, D-Washington; Representative Adam Smith, D-Washington; Former Oregon Representative David Wu.
