Missouri voters face a big change in how they chose their president. May 2022, the Missouri General Assembly voted to eliminate the March Presidential Preference Primary. Missouri Secretary of State Jay Ashcroft said in a news release “The selection of presidential nominations for the November 2024 will be under the direction of each established political party. Missouri statutes RSMo 115.776 created the caucus system for established state political parties for the purpose of nominating a candidate for the president of United States.”
