Which states have all Republican representatives in the House?

1. What the public data commonly reports — counts, not full state lists

Major public trackers and summaries emphasize totals (Republicans ~219–220 seats in the House in early 2025) and how many state delegations are controlled by each party (reported 30 state delegations Republican, 18 Democratic as of Nov. 20, 2025) rather than publishing an explicit, dated list of states with all-Republican House delegations in one place ^{[1] [2]}. The Green Papers provides seat-by-state tables for the 119th Congress but does not appear in the provided snippets to present a simple “all-Republican states” list accessible here ^[3].

2. Why a direct answer is harder than it sounds

Delegations change with special elections, resignations, deaths and appointments; Ballotpedia and news wires document several special contests and vacancies in 2025 (special elections, vacancies in Texas, New Jersey, Tennessee, Georgia, etc.) that alter which states have unanimously single-party delegations ^{[4] [5]}. Because the supplied sources emphasize evolving counts and note multiple vacancies and special elections in 2025, compiling a single authoritative list from them would require cross-referencing each state’s current members — an action not shown in the snippets ^{[4] [5]}.

3. What the available sources do confirm about partisan delegation control

The List of current United States representatives page (Wikipedia snapshot cited) explicitly reports that “As of November 20, 2025, Republicans control 30 state delegations and Democrats control 18 state delegations,” which is the most direct statement among supplied sources about whole-state delegation control levels ^[1]. Statista and Bloomberg-style summaries corroborate the Republican House majority numbers (≈219–220 Republicans) for the 119th Congress ^{[2] [6]}.

4. Examples of changing delegations from supplied reporting

Recent special elections and vacancies show why any “all-Republican” roster can flip quickly: Tennessee elected a Republican in a Dec. 2, 2025 special that shifted a seat to the GOP ^[5]. Ballotpedia’s special-election log notes multiple 2025 contests (Florida’s 1st, Arizona’s 7th, Texas special contests and others) that affect whether a state’s entire delegation is single-party ^[4]. These examples demonstrate the practical volatility behind delegation-level counts ^{[5] [4]}.

5. How to get a precise, current state-by-state list

The Green Papers’ “House Seats by State” table and the comprehensive “List of current United States representatives” are the two sources indicated here that, if fully consulted state-by-state, would allow construction of a definitive list for any given date ^{[3] [1]}. Neither the provided snippets include that state-by-state breakdown in full; therefore the sources here support the method but not a ready-made list ^{[3] [1]}.

6. Competing interpretations and limitations to note

Some outlets report a Republican majority as 219 seats (Bloomberg-style summary) while Statista lists 220 Republicans in the 119th Congress; both are consistent with a small GOP edge but differ by one seat depending on timing and how vacancies are counted ^{[6] [2]}. The supplied materials frequently note vacancies and special elections across 2025, so any static list risks being out of date the moment a special election or resignation occurs ^{[4] [5]}.

Conclusion — what you can reliably say from these sources: public trackers show Republicans hold a narrow House majority in the 119th Congress (about 219–220 seats) and that, as of a November 20, 2025 snapshot, Republicans controlled 30 entire state delegations versus 18 for Democrats ^{[2] [1]}. Available sources do not list, in the provided excerpts, the specific states whose full U.S. House delegations are entirely Republican at a single timestamp; constructing that list requires consulting the full state-by-state tables referenced ^{[3] [1]}.
