Return to the Guide to the Utah Legislature.
The scores below show how often (as a percent) each legislator votes with his/her party in the Utah legislature. If the legislator is a House Democrat and the majority of House Democrats vote "aye," then the legislator supports the party majority if he/she also votes "aye." I ignore votes where the legislator's party was tied. I also ignore votes where the legislator was absent.
Most votes pass by an overwhelming margin, with a majority of Republicans voting the same way as a majority of Democrats. (See details on party-line voting and consensus voting.) As such, the "overall" party support scores (which include all votes, even unanimous ones) tend to be inflated. We can get a more accurate estimate of each legislator's true party support score by looking only at "party-line" votes—that is, those few votes where the majority of Republicans votes against the majority of Democrats. By looking only at party-line votes, the "party support (party-line only)" column estimates how each legislator votes when his/her party really needs his/her support.
Years. By default, you will see scores from the most recent session for which I have data, which is 2025. Click on of the links below to see a different year.
