"Missouri Amendment 4...would change Missouri’s initiative petition process by requiring citizen-led constitutional amendments to earn broader statewide support and by making the full text of initiative petitions available to voters with their ballot.

...Liberty Alliance USA supports Amendment 4 because Missouri’s Constitution should not be rewritten without broad support and full transparency for voters.

Amendment 4 would prohibit foreign nationals, foreign governments, and foreign political parties from contributing to or spending money on Missouri initiative petition campaigns.

Missouri’s Constitution should be changed by Missouri voters, not influenced by foreign money. 

Amendment 4 also strengthens accountability for initiative petition fraud...

Stronger penalties for petition fraud protect voters, honest campaigns, and the constitutional amendment process itself. If special interests want to change Missouri’s Constitution, they should have to follow the rules and gather legitimate support from Missouri voters." - Liberty Alliance  

"In an era where direct democracy risks being hijacked by special interests and foreign influences, Missouri's Amendment 4 emerges as a vital shield for our state's foundational principles. Amendment 4 isn't about stifling voter voices—it's about ensuring those voices represent genuine Missouri values, free from fraud, deception, and external manipulation. 

...Amendment 4 proposes a balanced reform to the initiative petition (IP) process, addressing glaring abuses while preserving citizens' rights. With progressive groups already flooding the system with radical proposals, supporting Amendment 4 isn't just prudent—it's essential to protecting our families, jobs, and way of life." - Freedom Principle MO 

“Amendment 4 protects the Missouri Constitution from the out-of-state money and paid-signature campaigns that have spent the last decade treating our founding document like a billboard for rent. Under the current rules, a citizen-initiated constitutional amendment can be written by coastal interest groups, qualified with paid signature gatherers concentrated in a handful of urban ZIP codes, and passed with a bare statewide majority while most of Missouri’s counties vote no. Amendment 4 changes that. It requires citizen-initiated constitutional amendments to earn a majority in each of Missouri’s eight congressional districts, guarantees that voters can see the full text of an initiative with their ballot, and adds long-overdue protections against petition fraud and foreign contributions. Every corner of the state, from the Bootheel to the Northland, would have a seat at the table when our constitution is on the line.” - Missouri Republican Party 

“Amendment 4...would change the rules for citizen-led initiative petitions — the process Missourians have used since 1908 to put laws and constitutional amendments directly on the ballot. Today, those measures pass with a simple statewide majority. Amendment 4 would require a statewide majority plus a majority in EVERY Missouri congressional district.

The catch: politicians exempted themselves. Measures the legislature refers to the ballot still pass with a simple majority. Only initiatives that come from citizens face the higher bar.

Missouri has 8 congressional districts of roughly equal population. Under Amendment 4, a measure could lose if it falls short in any 4 districts — even by a single vote — regardless of the statewide total.

Amendment 4 was referred to the ballot by the Missouri General Assembly. It was not the product of a grassroots petition. The same body that wrote it then exempted itself from its rules — meaning politicians can still pass referred amendments with a simple majority, while citizen-led initiatives must clear the higher bar. That's not reform. That's rigging.” - Protect MOjority Rule

"This permanent constitutional amendment would make it nearly impossible for citizens to pass ballot measures.

Right now, a ballot measure passes in Missouri if it gets a majority of the votes statewide. Amendment 4 would change that.

Instead of using the total statewide vote, a measure would need to win a majority of votes in all eight of Missouri’s congressional districts in order to pass.

We should never vote to give up our own power and hand it over to politicians and the special interests who control them.

Amendment 4 takes away our power to pass laws - so politicians and special interests get all the power. Under Amendment 4, your vote can be cancelled by just ONE congressional district — that means just 5% of voters could vote down what the rest of the state approves." - Protect Majority Rule MO

“Politicians in Jefferson City are asking you to radically change the Missouri Constitution and vote away your power. They want to give a small minority of voters the power to veto what the majority of Missourians support.

Amendment 4 is the latest attack in a decades-long effort by politicians in Jefferson City to weaken Missouri’s citizen initiative process and make it harder for voters to have the final say. Written by politicians and backed by special interests, this proposed amendment would permanently rig the rules for citizen-led constitutional amendments." - Respect MO Voters

"The initiative petition is the only tool voters have to put constitutional changes on the ballot. Amendment 4 adds new hurdles that will allow a minority of voters to block a proposal—reducing statewide voter power.

Currently, a statewide simple majority is required to pass a citizen-initiated constitutional amendment. That’s how we passed Medicaid Expansion, Reproductive Freedom, and Minimum wage/Paid sick leave. None of these would have passed with the new Amendment 4 hurdles.

Amendment 4 will gut the people’s ability to make changes when our legislators don’t act." - League of Women Voters of Missouri
