U.S. Sen. Ron Johnson, R-Wis., came in at No. 5 on the National Journal’s ranking of the Senate’s most conservative members.
He was given a “composite conservative score” of 92.0 on a scale determined by selected roll-call votes from 2012. The Senate’s most conservative member, James Risch, R-Idaho, received a score of 95.8.
Johnson was ranked less conservative than three senators besides Risch: John Cornyn, R-Texas, Jim DeMint, R-S.C., and Pat Toomey, R-Pa.
The nonpartisan National Journal has rated members of Congress with this system for the last 30 years, with the goal of describing how they voted in comparison with one another.
