What It Does
Renews the existing 0.1% sales and use tax for 10 more years to fund state parks and soil and water conservation programs.
▌ Conservative Take
Missouri's state parks are a point of pride and rely on this small tax. The conservation trust fund has broad rural and outdoors support. This is a renewal — not a new tax. Conservative voters: YES — preserve Missouri's outdoor heritage.
For conservative voters: YES is the clear choice.
Campaign Finance
Conservation groups backing renewal. No organized opposition.
What It Does
Requires the Jackson County Assessor — who determines property values for tax purposes — to be an elected position rather than appointed.
▌ Conservative Take
After Jackson County's disastrous 2023 property tax reassessments that hit homeowners with massive increases, making the assessor accountable to voters is common-sense reform. Conservative voters: YES — accountability matters.
For conservative voters: YES is the clear choice.
Campaign Finance
No formal campaigns.
What It Does
Prohibits abortion in most cases. Separately prohibits gender transition procedures for minors under eighteen years old.
▌ Conservative Take
This is the most consequential measure on Missouri's ballot. After voters approved abortion access in 2024, Republicans are fighting back with a constitutional ban. It also codifies protection of minors from gender transition procedures. Two major cultural priorities in one amendment. Expect a fierce, expensive battle. Conservative voters: YES on both counts — life and child protection are non-negotiable.
For conservative voters: YES is the clear choice.
Campaign Finance
Expect multi-million dollar campaigns on both sides. This will be the most expensive ballot measure fight in Missouri history.
What It Does
Requires a majority of voters from each congressional district — not just a statewide majority — to approve constitutional initiative petitions. Also prohibits foreign nationals from contributing to ballot measure campaigns.
▌ Conservative Take
After progressives used the initiative process to pass abortion rights and marijuana legalization over the objection of rural Missouri, Republicans are adding geographic requirements to ensure statewide initiatives truly have statewide support — not just St. Louis and Kansas City votes. The foreign contribution ban is uncontroversial. Conservative voters: YES — rural Missouri deserves a voice.
For conservative voters: YES is the clear choice.
Campaign Finance
Progressive groups will heavily oppose this. Expect significant outside spending.
