Legislative scorecards are used to evaluate elected public officials based on voting record. Some scorecards are created by political advocacy groups with a focus on specific issues, while others are developed by newspapers and are broad in scope. Scorecards are meant to be used as a tool for voters to have a quick picture of whether their views align with a particular legislator's record.

Because scorecards can be specific to particular issues or general to a state’s legislative term, for example, each report should be considered on its own merits. Each entity that publishes these reports uses different methodologies and definitions for the terms used.

An overview for scorecards in all 50 states can be found on this page. To contribute to the list of Iowa scorecards, email suggestions to

Please see our writing guidelines if you would like to add results from an individual scorecard to this legislator's profile.


In 2012, the 84th Iowa State Legislature was in session from January 9 to May 9.[11]

Legislators are scored on "their records on constitutional principles and civil liberties."
Legislators are scored on their votes on "key conservative issues."
Legislators are scored on their votes with or against SC's official position.
