| Collapse all
- A generation of far-right policies haven't helped us. On average, Missourians learn less, earn less, and die sooner than when Republicans took over the Missouri legislature. It's time to try something different.
- Supporting and protecting public education is key to growing our economy and improving outcomes for our citizens.
- "Culture war" issues have hurt every aspect of Missouri. We should protect access to healthcare, reverse Missouri's total ban on abortion, and adopt proven anti-crime strategies, such as demanding responsibility from gun owners.

Scorecards
A scorecard evaluates a legislator’s voting record. Its purpose is to inform voters about the legislator’s political positions. Because scorecards have varying purposes and methodologies, each report should be considered on its own merits. For example, an advocacy group’s scorecard may assess a legislator’s voting record on one issue while a state newspaper’s scorecard may evaluate the voting record in its entirety.
Ballotpedia is in the process of developing an encyclopedic list of published scorecards. Some states have a limited number of available scorecards or scorecards produced only by select groups. It is Ballotpedia’s goal to incorporate all available scorecards regardless of ideology or number.
