The Ideology of Montana's Congressional Delegation in Historical Perspective
I'm working on a bunch of items for a chapter on the representational styles of Congressman Rehberg and Senator Tester. Here's a quick look at how they measure up ideologically compared to other senators and congressmen who have represented the state going back to the 1970s. The measure of ideology here is the Common Space score for the member, which is a measure of ideology calculated from congressional roll call data by Keith Poole and Howard Rosenthal. You can get details on the measurement at Professor Poole's website, VoteView. Common Space scores allow ideological comparisons across congressional chambers, which is why I use them and not the more common DW-NOMINATE scores. Negative scores are liberal, positive scores are conservative.
Interestingly, Rehberg is the most liberal of the Republicans who represented the state. And Jon Tester is fairly centrist. He's to the left of Senator Baucus, but nowhere near as liberal as Congressman Pat Williams or Senator John Melcher.
Just some food for thought on a Tuesday evening.
