Elections in Missouri are held to fill various local, state and federal seats.
In a 2020 study, Missouri was ranked as the 3rd hardest state for citizens to vote in, based on registration and identification requirements, and convenience provisions.
Absentee ballots may only be requested with a provided excuse and by mail or fax (with a copy of acceptable photo ID) by the second Wednesday prior to an election.
Residents may initiate ballot measures, including referendums and constitutional amendments.
Constitutional amendments may be initiated by a minimum number of valid signatures from the equivalent of 8% of votes cast in the last gubernatorial election from each of two-thirds of the state's congressional districts.
