FAQ: Why is Missouri's 2022 election ballot asking about a constitutional convention?

Thanks to a Missouri law, voters must be asked every 20 years whether they would like to call a convention to amend the state constitution. But since the question started being asked in 1962, Missourians have never voted "yes."
Toward the bottom of the Nov. 8 ballot, Missourians will find a question asking whether they would like to call a convention to amend the state’s constitution. Thanks to a state law, that question must be asked every 20 years. But what exactly is a state constitutional convention? And why would Missourians vote for it?

They haven’t in the past. Since 1962, constitutional convention invitations on statewide ballots have been turned down every two decades. In the last vote, in 2002, 65% of voters said “no.” Since the question has been asked, Missourians have never voted to hold a constitutional convention.
