Amendment 4

Missouri · November 3, 2026

What this measure does

Require the majority of voters from each congressional district to approve initiative petitions to amend the constitution, prohibit foreign nationals from contributing to ballot measure campaigns, among other provisions

A yes vote means Constitutional amendments would need approval from a majority of voters in each congressional district, and foreign nationals would be banned from contributing to ballot measure campaigns.
A no vote means Constitutional amendments would continue to work under current rules, and there would be no new restrictions on foreign contributions to ballot measures.
Simple explanation
Right now, if enough people sign a petition, a constitutional amendment can go on the ballot statewide. This measure says that instead, you'd need a majority of voters in each congressional district to approve it first — like needing buy-in from multiple neighborhoods instead of just the whole city. It also bans foreign nationals from giving money to ballot measure campaigns.
