Miles Ross

Miles Ross, left, executive director of the Missouri Republican Party, testifies Monday in favor of reinstating the Missouri presidential primary alongside state Rep. Brad Banderman, a St. Clair Republican sponsoring the legislation.

Missouri would join at least 14 other states with a “Super Tuesday” presidential primary in 2028 under a bill that would also bind the state’s delegate on the first ballot at national political conventions. 

During testimony Monday to the state Senate Local Government, Elections and Pensions Committee, leaders of the state’s two largest political parties agreed that restoring the primary would increase participation and elevate the state’s national political profile.
