So Pompeo is the most conservative of the Kansas delegation
National Journal rankings here http://www.nationaljournal.com/magazine/house-ratings-20120223
And most liberal and most conservative here http://www.nationaljournal.com/magazine/most-liberal-most-conservative-20120223
A 19 way tie for most liberal in the House and a ten way tie for most conservative.
Bit of a surprise that the new Wisconsin Senator would be the 2nd most conservative, well ahead of Idaho by 94.2 to 90.8 Might also note that the most conservative Senator had a score of 96 and the most liberal Senator only had a score of 88.7, which would put them in 7th place among conservatives.
So for locals it is
Kansas
Pompeo, 15th most conservative
Jenkins 36th
Yoder 47th
Huelskamp 74th
Surprising that, Huelskamp being more liberal on economic issues. Perhaps the details in how the ratings were measured would explain things.
Missouri
Clay - tied for most liberal
Akin - 114th most conservative (rated as more liberal than 31% of house members on social issues (wow))

Cleaver - 30th most liberal (rated as more conservative than 12% of house members on economic issues (???))
