The Missouri Democratic Party has released its plan for its party-administered presidential primary in 2024. The polls will only be open between eight a.m. and noon on March 23, because it costs a lot of money to hire people to administer the polls, and the limited hours will cost less money. People can also vote by mail, if they request a mail ballot by March 12, and if they have registered as a Democrat on their voter registration form.

Also, Democrats are letting 17 year-olds participate, if they will be age 18 by the general election.

Missouri is in its first year of letting voters register into a party. The procedure for doing this was passed in 2022 and took effect January 1, 2023. So far the Secretary of State is not releasing any data about how many voters have registered into each party. The bill that set up the procedure was HB 1878. For government-administered primaries, whether a voter has registered into any particular party has no bearing on whether that voter can or cannot vote in any particular primary. Thanks to Ken Bush for the news about the Democratic presidential primary.
