It's almost the end of this session of Congress, and looking back we can see who were the most conservative members.

The DW-NOMINATE score was developed byKeith Poole and Howard Rosenthal as a way to determine where legislators voted in relation to each other.

By looking at how each legislator voted on every roll call vote compared to the member's peers, DW-NOMINATE is able to show how liberal or conservative a Congressman or Senator is.

Over the course of a session, they develop a score based on how they vote compared to their peers. By looking at hundreds of roll call votes and comparing them mathematically, the DW-NOMINATE process is able to figure out where each member sits politically compared to other members.

The closer to -1 a member's score is, the more liberal they are. The closer to 1 a member's score is, the more conservative they are. At zero, a member is considered very, very centrist.

On this list, the closer the score is to 1, the more conservative the member is.

Knowing this, Poole is able to rank them in order of partisan tilt based only on how they voted in a single session.

As the 112th Congress approaches its end, we can look to the DW-NOMINATE score to see who were the most conservative members of the House of Representatives mathematically.

Score: 0.837

Votes: 837

A libertarian-leaning Republican, Amash is a vocal supporter of Rep. Ron Paul (R-TX) and one of the most far-right deficit hawks on the House Budget Committee.

But while Amash's conservative record is strong, he has occassionally bucked his party, most notably by voting against Paul Ryan's budget and against the deal to raise the debt ceiling. These votes apparently raised the the ire of the GOP House leaders, who voted last week to strip Amash of his position on the Budget Committee in the next Congress.

As an expert in political analysis and legislative scoring systems, I can attest to the significance of tools like DW-NOMINATE in assessing the political leanings of lawmakers. The DW-NOMINATE score, developed by Keith Poole and Howard Rosenthal, is a well-established method used to quantify the ideological positions of members of Congress based on their voting records. I have a deep understanding of how this scoring system works and its implications for understanding the political landscape.

DW-NOMINATE calculates scores for legislators by analyzing their roll call votes in comparison to their peers. The scores range from -1 (indicating a more liberal stance) to 1 (indicating a more conservative stance), with 0 suggesting a centrist position. This method allows for a comprehensive evaluation of a legislator's political orientation over the course of a session.

Now, delving into the specific information provided in the article:
