Which states had similar propositions to California Proposition 50 in 2024 and what were their results?
Executive Summary
California’s Proposition 50 — a 2025 measure to adopt a legislature-drawn congressional map temporarily and pause the Citizens Redistricting Commission’s map — had no clear, direct analogue on state ballots in 2024, based on the available reporting. Reporting from 2024 and 2025 shows two distinct clusters of activity: criminal-justice ballot measures in several states during 2024 (Arizona, Colorado, Missouri, Nevada and California) and redistricting battles and map adoptions occurring mainly in 2025 in Texas, Missouri, and North Carolina that motivated California’s 2025 action [1] [2] [3] [4] [5]. The materials provided do not identify other states that placed a proposition matching Prop 50’s specific mechanism — temporarily replacing an independent commission’s congressional map with a legislature-drawn map contingent on a single vote — on a 2024 ballot, nor do they report 2024 results that mirror Prop 50’s aims [6] [7].
1. Why the question matters: a national fight over maps and timing
The provided reporting frames Prop 50 as a reaction to a larger national redistricting conflict — particularly Texas’ partisan maps and subsequent map changes in other states — rather than as part of a wave of identical 2024 state ballot measures [4] [8]. California’s effort is cast as a strategic, targeted response to 2025 map changes elsewhere and to shape the composition of the U.S. House for subsequent elections, not as a replication of a 2024 template. The sources chronicle litigation, campaign finance, and political actors pressing the case in California — including large contributions on both sides and high-profile supporters and opponents — underscoring that Prop 50 is rooted in a specific political contingency following redistricting moves outside California [4] [7].
2. What 2024 did show: criminal-justice measures, not congressional map swaps
The 2024 ballot landscape emphasized crime and criminal-justice initiatives across multiple states, not congressional map swaps like Prop 50. Voter guides and post-election summaries list measures in Arizona, California, Colorado, Missouri, and Nevada addressing incarceration, sentencing, and related issues; some states removed language on involuntary servitude while others pursued tougher sentencing provisions [1] [2] [3]. Those 2024 measures produced mixed results and signaled competing policy directions on criminal justice, but they are distinct in purpose and design from Prop 50’s redistricting mechanics. The 2024 measures therefore do not offer direct precedents for a temporary legislative map override of an independent commission’s congressional lines [2] [3].
3. Where similar actions did occur: redistricting moves in 2025, not 2024
The closest analogues identified in the reporting are state redistricting moves and new maps adopted around 2025 — notably in Texas, Missouri, and North Carolina — which prompted California’s proposed response in Prop 50 [4] [5]. Those actions were described as efforts that could alter partisan control of the U.S. House and motivated California’s advocates to pursue an off-cycle remedy. The sources indicate California’s measure was explicitly linked to the national battle over partisan gerrymandering, but they do not document any state in 2024 adopting a proposition that functionally matched Prop 50’s mechanism or immediate political objective [4] [8].
4. Conflicting framings and donors: what the coverage highlights
Coverage of Prop 50 emphasizes contest between political strategies and powerful donors: the Yes campaign raised large sums from Democratic-aligned groups to counter Republican-led redistricting elsewhere, while high-dollar opposition funding came from individual donors and groups framing the measure as an overreach [4]. By contrast, the 2024 measures discussed in the sources drew attention to criminal-justice policy debates and showed divergent voter choices — some states approved reformist language, others backed punitive measures — indicating a different set of mobilizing forces and donor dynamics than those driving Prop 50 [2] [3]. The available analyses underscore that Prop 50’s motivations and funding were reactive to 2025 map changes rather than derivative of 2024 ballot campaigns.
5. Bottom line and gaps: what the supplied reporting cannot confirm
Based on the supplied material, the key factual takeaway is that no state in 2024 is documented as having an identical proposition to California’s Prop 50; 2024 saw important ballot fights, primarily on criminal-justice topics, while the redistricting maneuvers that provoked Prop 50 occurred in 2025 [1] [2] [4] [5]. The reporting set contains gaps: it does not present exhaustive national ballot data for 2024 nor does it document any attempt in 2024 to temporarily override an independent congressional redistricting commission via voter-approved adoption of a legislature-drawn map. If you want a definitive, state-by-state confirmation, compiling official 2024 ballot summaries and state election returns would be the next necessary step; the current sources point to context and motive rather than to a roster of matching 2024 propositions and results [3] [7].
