My friends in political science used to talk a lot about “roll call voting” analysis over lunch in Perry Cafeteria at Mississippi State University. I was a member of the Faculty Forum who held a reserved anteroom for lunch in this beautiful arched building. I learned a lot from experts in other disciplines that a situation to discuss them might have not presented itself otherwise. On roll call voting in Congress, unless the body excuses itself from such an explicit vote, the Clerk records how each House or Senate member voted on a piece of legislation or rule change or other formal matter before the body. The results of such studies reveal how patterns of block-voting occur, whether on all issues or on certain ones.
