The Republican caucuses will take place in person across the state beginning at 11 a.m. Eastern time. Instead of secret ballots, participants will move around a room and form groups that will determine how many representatives each candidate will have at district and state conventions held later.
Missouri voters may affiliate with a party via their local election authority. While voters are not required to be affiliated with the Republican party in order to caucus, the party is requiring participants to sign a pledge declaring their allegiance. Missouri Democrats will hold a primary on March 23.
