Voting Records


Voting records for U.S. senators and representatives from Missouri are readily available through Project Vote-Smart.   You can use this website to find a legislator's voting record by subject.

Unfortunately, voting records for legislators in the Missouri state House and Senate are not arranged either by legislator or by subject in the Missouri legislative journals.  Rather, the journals are arranged chronologically.  To see how a legislator voted, first you must identify a bill that interests you. Next, determine the date that the bill came to a vote. Finally, locate that date in the legislative journals and browse until you find the roll call vote.
