U.S. Rep. Bob Latta (R., Bowling Green)- whose 5th District includes most of West and South Toledo - is the 10th most conservative member of the U.S. House of Representatives.
U.S. Rep. Marcy Kaptur (D., Toledo) - whose 9th District includes the rest of Toledo - is the 293rd most conservative (137th most liberal).
Those ratings come from the National Journal, which analyzed 111 House votes in the 113th Congress.
Latta's northwest Ohio Republican colleague Jim Jordan (R., Urbana) - a leading House Tea Partier - was more liberal than Latta, at 65th. The Journal says that Jordan is more conservative than Latta on economic issues, but more liberal than Latta on social and foreign issues.
Another Ohioan, Steve Chabot of the 1st District in the southwest corner of Ohio, was ranked as the single most conservative Congressman. Chabot celebrated that fact on his campaign blog.
Here is the National Journal's package and the bills on which their analysis was based.
Sherrod Brown (D., Ohio) was tied for the 13th most liberal senator (he was tied for 1st in 2011). Rob Portman (R., Ohio) is the 72nd most liberal senator.
