Ballot measures

Missouri Amendment 2, Medicaid Expansion passed in the August 4 primary.

Missouri Amendment 3, Redistricting Process and Criteria, Lobbying, and Campaign Finance Amendment is to amend the state constitution to lower thresholds for lobbyists' gifts, lower campaign contribution limits for state senate campaigns and reverse changes to the redistricting process brought about by the passage of 2018's Missouri Amendment 1, known as "Clean Missouri". That amendment (aimed to prevent gerrymandering) delegated redistricting to a nonpartisan state demographer and citizens' commission as opposed to the status quo ante of it being left to a bipartisan commission appointed by the governor.
