Floor power ratings, 2007-2019

How influential is each Utah legislator? Here's one way to measure it: How often does each legislator get his or her way when voting on a bill?

Suppose that every time a particular legislator votes "aye" on a bill it passes, and every time he votes "nay" on a bill it fails. That legislator would have a 100% power rating. Now, suppose that every time another legislator votes "aye" on a bill it fails, and every time he votes "nay" it passes. That legislator would have a 0% power rating.

To prevent all the ratings from skewing toward 100%, I omit the MANY near-unanimous votes where more than 80% of legislators voted the same way. The "Avg # votes" column tells you how many votes from each session were used (on average) to calculate each year's score.

Floor power vs backroom power. These rankings measure each legislator's power in FLOOR votes. Note that it's an entirely different trick to influence which bills even come to the House or Senate floor for a vote. Getting a bill through the Rules Committee, onto a standing committee agenda, and through late-session bill prioritization requires backroom power, not floor power. One way to estimate backroom power is to see how many of a legislator's sponsored bills pass.

Leading vs following. I've put a positive gloss on these scores by calling them "floor power," implying sway over fellow lawmakers. But these scores could just as easily be measuring a lawmaker's tendency to follow the crowd. Your call.

Republican scores are in red, Democratic scores are in blue.
