No Requirement to Register by

Party Affiliation

 

Missouri law DOES NOT require an individual to register by political party.

Many states do have this requirement.  Please do not indicate your political party affiliation

as you fill out your voter registration application. 

 

However, if a voter chooses to participate in the August Primary in even-numbered

years, the voter will be asked by the Election Judges which party ballot the

voter wishes to vote.  No record is kept of the voter's selection by the County Clerk's Office.

 

Missouri has an  'open-primary' system.
