People often focus more on what politicians say than on what they do. Those two things are often not in accordance, due to factors within their control and not within their control. My preference is to look at how candidates actually legislate. However, no one that I know of puts out this information in an easy-to-read way. So, I have tried below to compile all of the legislative scorecards I could find for two Arizona candidates. I hope you find it useful.
