How many state legislatures have zero Republican members and which states are they?
Executive summary
Available sources in the provided set do not list any state legislatures that have zero Republican members and do not provide a direct count of chambers entirely without Republicans; Ballotpedia and MultiState show party control summaries but do not state that any chamber has zero Republicans (not found in current reporting) [1] [2].
1. What the sources do say about partisan control of state legislatures
Nationwide overviews in the supplied materials focus on which party controls chambers or governments rather than on the presence or absence of any members from a party. MultiState’s 2025 summary lists 18 full Democratic state governments, 28 full Republican governments and four split controls as of December 2, 2024, but that is about trifectas and chamber control, not about chambers with zero members of one party [2]. Ballotpedia’s partisan-composition reporting provides counts of seats held by each party across chambers and notes majorities, ties, and multipartisan coalitions (for example Alaska and Minnesota arrangements), but it does not claim any state legislative chamber contains no Republican members [1].
2. Why “zero Republican members” is different from “Democratic control”
A chamber can be fully controlled by Democrats without having literally zero Republican members; “control” refers to which party holds a majority. Ballotpedia’s data emphasize seat counts—nationally Republicans held majorities in more chambers and a larger share of seats in the periods reported—highlighting that most reporting distinguishes majorities/ties/coalitions rather than reporting chambers with no members of a major party at all [1]. MultiState similarly categorizes states by partisan control and trifecta status, not by absolute absence of members of the other party [2].
3. What the sources explicitly note about exceptions and shared power
When a chamber lacks a simple majority for one side or features an unusual arrangement, the sources call that out: Ballotpedia documents power-sharing or multipartisan coalitions in Alaska and a tied chamber in Minnesota [1]. These entries demonstrate that the sources report atypical legislatures when they exist, suggesting they would likely note a chamber with zero Republicans—yet no such claim appears in the provided excerpts [1].
4. Limits of the available reporting for this query
The supplied search results do not include a direct, current roster-by-roster accounting that would allow us to assert definitively whether any state legislative chamber currently has zero Republican members; Ballotpedia provides detailed tables but the snippets provided here do not show any chamber with zero Republicans and do not include full rosters in the excerpts [1]. The MultiState and NCSL items summarize control but do not list member composition at the level needed to confirm a “zero Republicans” condition [2] [3].
5. How one would verify the claim with these sources
To answer the question definitively using these outlets, one would consult Ballotpedia’s full “Partisan composition of state legislatures” tables or the National Conference of State Legislatures’ (NCSL) state partisan composition pages and inspect each chamber’s membership lists or seat tallies for the presence of any Republican-affiliated members [1] [3]. MultiState’s maps and data could provide corroborating chamber-level control details but, again, would need to be paired with membership rosters to prove absolute absence [2].
6. Competing perspectives and possible pitfalls
Public summaries that report “Democratic control” can be misread as meaning “no Republicans at all.” The sources provided distinguish majority control, ties, and coalitions—Ballotpedia explicitly records tied chambers and multipartisan coalitions rather than treating those as single-party rule [1]. If a reader sees a state labeled “D” (for Democratic control) on a MultiState map, they should not assume Republicans are completely absent; the labeling indicates which party holds the majority, not that the minority party has zero members [2].
7. Bottom line and recommended next steps
Based on the provided reporting, there is no documented claim in these sources that any U.S. state legislative chamber currently has zero Republican members; the available excerpts do not mention any such chamber and instead report majority control, ties, and coalitions [1] [2]. To get a conclusive, chamber-by-chamber answer, consult Ballotpedia’s full partisan-composition tables or the NCSL’s state-partisan-composition pages and review each chamber’s seat-by-seat listing [1] [3].
