Missouri Municipal Ordinance Implementation

Tier 3 — Significant Barriers
4Target Cities
Home RuleHome Rule

Missouri presents the strongest opportunity within the Plains and Mountain West batch for municipal ordinance strategies enforcing 18 U.S.C. § 592. It is the only state in the region with an existing statutory polling place firearms restriction, the nation's oldest home rule tradition (dating to 1875), and a narrow but real municipal exception for regulating open carry. The combination of progressive urban centers (St. Louis, Kansas City, Columbia), robust coalition infrastructure centered on the Missouri Voter Protection Coalition, and the instructive SAPA litigation precedent create a viable — if legally contested — pathway for municipal action.

Home Rule Authority

Missouri's home rule tradition dates to 1875 — among the oldest in the nation. Mo. Const. Art. VI, Section 19(a) provides charter cities with "all powers which the general assembly of the state of Missouri has authority to confer upon any city, provided such powers are consistent with the constitution of this state and are not limited or denied either by the charter so adopted or by statute." This is an exceptionally broad grant. Any city with 5,000+ population may adopt a charter under Mo. Rev. Stat. Section 82.020. Approximately 32+ home rule charter cities exist, including St. Louis, Kansas City, Springfield, Columbia, Independence, and St. Joseph. However, Missouri courts have applied Dillon's Rule even to home rule cities, construing powers narrowly when in doubt.

St. Louis City holds unique status as an independent city since 1876 — not part of any county, one of only three independent cities in the United States outside Virginia. St. Louis operates as both a city and county-equivalent entity, performing circuit court functions, election administration, and revenue collection. Its Board of Aldermen (14 aldermen plus president) serves as the legislative body. This dual authority gives St. Louis broader regulatory scope and fewer jurisdictional overlaps.

Kansas City is a charter city under Art. VI, Section 19(a), with a 13-member City Council (6 district, 6 at-large, plus mayor). However, Kansas City faces a fundamental limitation: the Kansas City Police Department is uniquely controlled by a state-appointed Board of Police Commissioners — the city does not fully control its own police department, creating a significant obstacle for an ordinance directing police non-cooperation.

Key case law supports broad home rule. City of Cape Girardeau v. Joyce, 884 S.W.2d 33 (Mo. App. 1994), affirmed that home rule cities have broad authority to act even in areas touching on state interests. Enright v. Kansas City, 536 S.W.2d 17 (Mo. banc 1976), confirmed the expansive reading of Section 19(a). Under the "statewide vs. local concern" test from Flower Valley Shopping Center, Inc. v. St. Louis County, the ordinance should be characterized as governing municipal resource allocation (traditional local concern) rather than election administration (state concern).

Preemption Landscape

The critical barrier is RSMo 21.750, the firearms preemption statute, which "occupies and preempts the entire field of legislation touching in any way firearms" — though a narrow exception permits municipalities to regulate open carry (RSMo 21.750(3)(1)). HB 726/SB 74 (2025) would repeal this open carry exception, and pending legislation also proposes expanding the electioneering buffer zone from 25 to 50 feet. The critical distinction: no such comprehensive field preemption language exists for election-related municipal resource allocation.

Missouri's Republican-dominated legislature has engaged in extensive preemption of local progressive ordinances: minimum wage (2017, after St. Louis's 2015 increase); plastic bag bans (2015); paid sick leave repeal (2025, overriding a voter-approved measure); and pending housing protection preemption. This pattern establishes that if this ordinance gains traction, retroactive preemption should be anticipated.

Missouri's Second Amendment Preservation Act (SAPA) is the most instructive precedent. SAPA (Mo. Rev. Stat. Sections 1.410-1.485, enacted 2021) penalized local law enforcement for enforcing federal gun laws with $50,000 fines. In U.S. v. Missouri (W.D. Mo. 2023), Judge Brian Wimes struck down SAPA as unconstitutional "interposition" violating the Supremacy Clause. The Eighth Circuit unanimously affirmed (August 2024), and the Supreme Court declined certiorari (October 2025). SAPA failed because it (1) declared federal laws "invalid" and (2) penalized cooperation with federal enforcement. The proposed election protection ordinance avoids both errors — it enforces federal law (18 U.S.C. Section 592) and does not declare any federal statute invalid.

The anti-sanctuary statute Mo. Rev. Stat. Section 67.307 (enacted 2019) prohibits municipalities from adopting policies limiting cooperation with federal immigration authorities, with state grant eligibility penalties. However, Section 67.307 is immigration-specific and does not broadly prohibit refusal to cooperate with all federal agencies. The election protection ordinance's enforcement-of-federal-law framing further distinguishes it.

Constitutional Basis

Mo. Const. Art. I, Section 25 — "all elections shall be free and open" — provides an affirmative state constitutional right supporting the ordinance's voter protection purpose. This language is particularly powerful because it enables the city to claim it is protecting a state constitutional value, not merely asserting local preference. Combined with the federal foundation of 18 U.S.C. Section 592 and the Voting Rights Act Section 11(b) (52 U.S.C. Section 10307(b)) prohibiting voter intimidation, the ordinance draws from multiple constitutional wells simultaneously.

Missouri's Constitution, Article I, Section 23, establishes strict scrutiny for firearms regulations, one of the nation's strongest state-level gun rights provisions.

Section 2: Statute Localization Kit

Key Missouri Statutes:

  • RSMo Chapter 115 — Election Authorities and Conduct of Elections (Title IX)
  • RSMo 115.023 — Election authority conduct
  • RSMo 115.105-115.111 — Challengers and watchers (one challenger per polling place per party, names submitted 4 business days prior; watchers must take oath per RSMo 115.109)
  • RSMo 115.409 — Polling place access (strictly limits who may enter a polling place to authorized personnel, election judges, credentialed watchers/challengers, law enforcement at election officials' request)
  • RSMo 115.631 — Felony election offenses (up to 5 years, $10,000 fine)
  • RSMo 115.635 — Misdemeanor voter intimidation (up to 1 year, $2,500 fine)
  • RSMo 115.637 — Electioneering buffer zone (25 feet, pending expansion to 50 feet)
  • RSMo 571.215(2) — Prohibits carrying concealed firearms within 25 feet of any polling place on any election day, even for CCW permit holders
  • RSMo 571.030(8) — Prohibits concealed firearm possession in any election precinct on election day for non-permit holders
  • RSMo 571.107 — Municipalities may prohibit firearms in government-owned buildings (though without criminal penalties)
  • RSMo 21.750 — Firearms preemption statute; subsection (3)(1) permits municipalities to regulate open carry
  • Mo. Const. Art. VI, Section 19 — Home rule charter authority
  • Mo. Const. Art. I, Section 25 — "All elections shall be free and open"

Missouri lacks a specific state-level private right of action for voter intimidation. Enforcement relies on criminal prosecution under RSMo 115.631/115.635 and federal civil rights claims. No state voting rights act exists.

Section 3: Target City Analysis

St. Louis City — Population ~301,578 — Passage Probability: HIGH

Mayor Tishaura Jones (Democrat, progressive) leads an overwhelmingly Democratic Board of Aldermen. St. Louis attempted a minimum wage increase in 2015 (preempted), and Jones joined Kansas City Mayor Lucas in opposing SAPA. As an independent city-county, St. Louis exercises both municipal and county authority with no county government overlap. The Board of Election Commissioners is governor-appointed (not city-controlled), but the ordinance targets city resources rather than election administration. St. Louis is the optimal first target in Missouri.

Kansas City, MO — Population ~508,090 — Passage Probability: MEDIUM-HIGH

Mayor Quinton Lucas (Democrat, progressive) leads a heavily Democratic council that has passed progressive housing and anti-discrimination ordinances. The critical limitation is state control of KCPD through the Board of Police Commissioners — the city cannot unilaterally direct KCPD cooperation policies. The ordinance in Kansas City must be drafted to focus on city departments and facilities other than KCPD.

Columbia, MO — Population ~126,254 — Passage Probability: MEDIUM

Charter city with progressive-leaning council (University of Missouri). Columbia's police department was among the first to withdraw from ATF task forces under SAPA, demonstrating institutional receptiveness to federal non-cooperation policies.

St. Louis County — Population ~1,004,125 — Passage Probability: MEDIUM-HIGH

Charter county with Democratic County Executive Sam Page. Combined with St. Louis City, would cover the entire metro core. A county ordinance combined with St. Louis City's would provide umbrella coverage across the entire metro St. Louis region. Only St. Louis County and Jackson County have adopted home rule charters under Mo. Const. Art. VI, Section 18.

Section 4: Coalition Directory

Missouri Voter Protection Coalition (MOVPC) — Director and General Counsel Denise Lieberman, Washington University Law faculty. Nonpartisan statewide voter advocacy network; leads every major voting rights lawsuit; coordinates statewide Election Protection with ACLU, Lawyers' Committee, and Demos.

ACLU of Missouri — Executive Director Luz Maria Henriquez, St. Louis. Most active voting rights litigator in state; filed multiple election lawsuits on voter ID and absentee access.

Empower Missouri — Executive Director Mallory Rusch, Jefferson City. Anti-poverty advocacy with deep understanding of preemption battles; vocal local control advocate.

Action St. Louis — Grassroots racial justice organization with strong community organizing in Black communities; focus on voter engagement.

Missouri Faith Voices — Executive Director Cassandra Gould. Faith-based coalition for social justice; effective in mobilizing communities of color.

Additional Partners: League of Women Voters of Missouri (co-plaintiff in voter ID lawsuits), Missouri NAACP (President Nimrod Chapel Jr.), Organization for Black Struggle (Executive Director Jamala Rogers), VozKC (Kansas City Latino advocacy), Missouri Municipal League (Executive Director Richard Sheets — natural ally on local control), Brennan Center for Justice, and Campaign Legal Center.

Section 5: Election Security Infrastructure

Secretary of State Denny Hoskins (R) took office in January 2025 after winning election in November 2024. The Elections Division, co-directed by one Republican and one Democrat, administers all statewide elections and maintains the Missouri Centralized Voter Registration System (MCVR). The election code resides in Title IX of the Missouri Revised Statutes, primarily Chapter 115 — Election Authorities and Conduct of Elections.

Missouri legislators introduced 141 election-related bills in 2024 alone. SJR78 (2024) prohibited ranked-choice voting. The state uses paper ballot/optical scan systems exclusively across all jurisdictions, primarily ES&S DS200 precinct scanners and ExpressVote ballot marking devices, with some Unisyn Voting Solutions equipment. All jurisdictions produce voter-verified paper ballots.

Missouri did not join the 19-state EO 14248 lawsuit filed April 3, 2025. The current Attorney General is Catherine L. Hanaway (R), Missouri's 45th AG and first woman to hold the position, appointed by Governor Mike Kehoe (R) on August 19, 2025. She succeeded Andrew Bailey, who resigned to become FBI Co-Deputy Director. Hanaway, a former U.S. Attorney and Missouri House Speaker, has focused on Medicaid fraud and consumer protection rather than culture-war litigation.

Cybersecurity Infrastructure & Capabilities

The Missouri Office of Cyber Security (OCS) within the Information Technology Services Division is led by State CISO Shawn Ivy, appointed June 2024. OCS protects over 60,000 state technology devices using a zero-trust, layered defense built on NIST frameworks, assessing more than 30,000 networked assets routinely. Theresa Frommel serves as Enterprise Cyber Risk Manager.

Missouri's total federal HAVA Election Security grant allocation through FY2022 is $16,584,673 ($7.23M in FY2018, $8.13M in FY2020, $1.22M in FY2022), with $2.23M in state matching funds for a combined investment of $18.8 million. The allocation breakdown is 57% cyber and physical security, 24% voter registration systems, and 19% voting equipment.

The Missouri National Guard Cyber Team operates a full-time cyber threat response team at Jefferson Barracks in south St. Louis County — reportedly the first state-level full-time Guard cyber unit in the nation. The state also hosts an Army National Guard Cyber Protection Team. Missouri participates in information-sharing frameworks. CISO Ivy stated in 2025 that federal service reductions have had "limited" overall impact due to Missouri's layered, state-driven security approach.

Physical Security & Polling Place Protections

Buffer zone: 25 feet from the polling place under RSMo 115.637, with pending legislation to expand to 50 feet. Within this zone, wearing political apparel, distributing campaign literature, and collecting petition signatures are prohibited. Violation is a Class four election offense (up to 1 year imprisonment, $2,500 fine). RSMo 115.409 strictly limits who may enter a polling place to authorized personnel, election judges, credentialed watchers/challengers, law enforcement at election officials' request, and specific other categories.

Missouri is the strongest state in the Plains and Mountain West batch for polling place firearms restrictions. RSMo 571.215(2) prohibits carrying concealed firearms within 25 feet of any polling place on any election day, even for CCW permit holders. RSMo 571.030(8) further prohibits concealed firearm possession in any election precinct on election day for non-permit holders. However, open carry near polling places is not explicitly prohibited by state statute — a significant gap. Missouri became a constitutional carry state on January 1, 2017.

The firearms preemption statute RSMo 21.750 broadly preempts municipal firearms regulation, though municipalities may regulate open carry of firearms (RSMo 21.750(3)(1)) and may prohibit firearms in government-owned buildings (RSMo 571.107) — though without criminal penalties.

Poll watchers are governed by RSMo 115.105 (one challenger per polling place per party, names submitted 4 business days prior) and RSMo 115.107 (watchers must take oath per RSMo 115.109). Law enforcement may be present at polling places "at the request of election officials or in the line of duty" (RSMo 115.409).

Missouri lacks a specific state-level private right of action for voter intimidation. Enforcement relies on criminal prosecution under RSMo 115.631/115.635 and federal civil rights claims. Active litigation includes the SAPA case in the Eighth Circuit and the pending HB 726/SB 74 to strengthen firearms preemption.

Key strategic advantage unique to Missouri: The state itself endorsed the principle of non-cooperation with disfavored federal enforcement through SAPA. While SAPA was struck down for different reasons (declaring federal law invalid and penalizing cooperation), Missouri's political establishment validated the underlying concept. The election protection ordinance uses the same structural principle from the opposite political direction — a powerful messaging asset.
