The National Journal
recently rated the members of Congress, assigning each congressman either a liberal or conservative score.
The most liberal senator is Ted Kennedy (D-MA). Wayne Allard (R-CO), Jeff Sessions (R-AL), and Tom Coburn (R-OK) tied for the most conservative voting record in the senate.
Of the 40 most conservative members of congress (15 in the Senate and 25 in the House), only one is from a blue state: Rep. Bill Shuster (R-PA), who has the 6th most conservative score in the House of Representatives.
The same list of liberals include six from red states, including two from Georgia, and one each from Arizona, Iowa, North Carolina, and Ohio. Cynthia McKinney (D-GA) is the second most liberal House member.
The most conservative congressmen were all Republicans while the most liberal were all Democrats. Would this have been the case 20 years ago? It certainly wouldn't have been the case 50 years ago.
