As of July 12, 2025, here are the number of Missouri voters registered into each qualified party: Republican 120,449; Democratic 110,844; Libertarian 4,772; not registered into any party 4,063,782.
The Missouri voter registration form did not ask about party affiliation until 2022, when the legislature passed HB 1878 providing that the form should ask about party membership. The overwhelming majority of Missouri voters have not had to register in the past three years, so naturally not many voters have used the new form. That is why so few voters are registered with any of the three parties.
Missouri continues to have an open primary. Any voter can ask for any party primary ballot. If the voter has chosen a party, that has no concrete bearing on election administration. Arkansas is similar to Missouri.
Ballot Access News has never before reported on party membership in Missouri.
There should be no government financed or administered primaries and no level of government should keep track of which party or parties if any voters identify with. That should be strictly an internal task for parties themselves using their own methods, resources, and criteria. As should be the selection of the method by which they nominate or endorse candidates (or office holders, if or when we ever get rid of the idiotic requirement for parties to choose would be officeholders ahead of the election for every office they want to contest regardless of the chances of winning it).
SHOW ME THE REGISTRATION LISTS IN THE SHOW-ME STATE AND I’LL SHOW YOU THE NEXT PURGE LIST.
