Ideology scores for the Utah House of Representatives, 2015

Political scientists have developed advanced algorithms that can calculate each legislator's ideology score based on his or her legislative voting record, called a NOMINATE score (it's an acronym, hence the caps). Usually these scores are used to study Congress. They are difficult and time-consuming to calculate, so they are not available for most states. As part of my research, I calculated scores for Utah legislators. Important caveats:

  1. Ideology scores have no scale. There is not a number that means "liberal." Scores only have relative meaning. A lower score is more liberal than a higher score.
  2. Scores are only comparable within a single chamber, within a single year. You cannot compare House scores to Senate scores, and you cannot compare 2010 scores to 2011 scores. (That's because of caveat #1: Scores have no scale.)
  3. Zero does not mean "moderate," it just means "the middle of this group of legislators." Since Utah's legislature is very conservative, the most moderate Utah legislators would seem very conservative on a national scale. Even scores below 0 probably indicate a pretty conservative legislator in these scores.

You can find a thorough discussion of these ideology scores at the Utah data points blog.
