JEFFERSON CITY — Missouri voters soon will be asked to curb their own legislative powers by making it harder to change the state constitution following Senate approval Friday of a so-called initiative petition reform bill.
Senators mostly along party lines gave final approval to a plan designed to weaken a citizen petition process that has led in recent years to increases in the minimum wage and the legalization of abortion, recreational marijuana and sports betting.
Republican lawmakers say the change is needed to protect rural voters from getting drowned out by urban interests and stop undue influence from big-money advertising and signature-collecting campaigns from liberal donors out of state.
“Our state’s constitution has been under assault for years now,†said Senate President Cindy O’Laughlin in a Facebook post during the debate, “and it is time we stop this.â€

Democrats, however, decried the proposal as an unjust power grab that would make it impossible for the residents to directly influence their government. They said they were hopeful voters wouldn’t approve it.
“I know that people are smart,†Sen. Maggie Nurrenbern, D-Kansas City. “I know the people of Missouri are not going to yield their power to the few.â€
The 21-11 vote with only two dissenting Republicans ended a two-week special session called by Gov. Mike Kehoe to advance key Republican interests, including the redistricting of a Kansas City congressional seat to flip it to the GOP.
The measure was not debated before Republicans used a procedural maneuver to overrule objections and head toward a vote.
Afterward, progressive groups that have advocated for ballot measures in recent years lamented its passage.
Caitlyn Adams, voter action director of Jobs With Justice, which pushed for a minimum wage increase, said that despite thousands of people showing up to protest the bill earlier in the week, Republican lawmakers “attacked direct democracy by attempting to end majority rule.â€
“It’s up to us to come together and reject this on the ballot,†Adams said in a statement.
The measure will be on the ballot next year.
