Missouri is one of the few states that does not require a voter to state his political party affiliation on his registration. Many voter registration groups use a generic form that is valid in all states. This form may include a box or an area for a voter to indicate his political party. Missouri registrants need not write or place a check mark in this area.
Missouri has an August statewide primary election in each even-numbered year. The primary is an election contest between members of the same political party. For example, several candidates of the same political party may file for the position of County Treasurer. The August election will determine which candidate will face the candidate for that same position from the opposing political party in the November general election.
Our election judges will ask you which political party’s ballot you would like to vote. All candidates of one political party will appear on your ballot. No record of your political party selection is kept by the County Clerk or the state of Missouri.
