National Journal: McCain Tops List of Most Conservative Senators In the ideological rankings of members of Congress that the National Journal released Thursday, one name stands out. Senator John McCain, Republican of Arizona. Once a self-described maverick whose conservative ranking in the survey was among the lowest in the Senate, Mr. McCain this year tied with a handful of other Republican senators as the most conservative of all, according to a release provided to The Caucus by the National Journal. The news organization ranked lawmakers on the ideological spectrum based on about 100 key votes in 2010. The annual survey assigns point values to the votes, and Republicans receive scores. The closer to 100, the more conservative they are. Mr. McCain earned an 89.7, putting him in a tie with senators like Jim DeMint of South Carolina, John Cornyn of Texas and John Barrasso of Wyoming. No one scored higher than that in this years survey. That contrasts with previous years, when Mr. McCain regularly ranked as somewhere near the 45th most conservative member of the Senate.
