Which states currently have no Republican representation in Congress?

1. What the main sources actually say about partisan balance in Congress

Congressional membership listings and party-breakdown pages provide totals and delegation control but do not produce a ready-made list of states that lack any Republican members. The House roster page notes there were “433 representatives and 2 vacancies” and summarizes that Republicans control 30 state delegations versus Democrats controlling 18 as of December 4, 2025 ^[1]. The House Press Gallery also offers party breakdowns but presents aggregate numbers rather than enumerating states that are entirely without Republican representation ^[2].

2. Why you won’t find a simple “zero-Republican” state list in these sources

The available reporting emphasizes overall party counts and which party controls a state delegation, not the precise per-state composition that would identify states with no Republicans at all. The Wikipedia listing of current representatives is a comprehensive roster, but the snippet and summary text in the provided extract do not include a compiled list of states that lack Republican members; they only describe totals and select vacancies ^[1]. The House Press Gallery likewise gives party breakdown totals but not the granular, state-by-state “none of one party” inventory ^[2].

3. How you could determine which states currently have no Republican members in Congress

To answer the original question using the available resources, a journalist or researcher must cross-reference the full House roster—reading each state delegation entry on the “List of current United States representatives” page—and identify states where all listed representatives are Democrats or non-Republican, and then check the Senate seats for each state ^[1]. The provided sources show that this task is possible in principle from the roster ^[1] but that the supplied snippets do not do the work for you ^{[1] [2]}.

4. Limits of the provided material and what’s not covered

Available sources do not mention a compiled list of states that presently have zero Republican members in either chamber. The Wikipedia and House Press Gallery excerpts give totals and note vacancies but do not report state-by-state lists of “no-Republican” delegations in the snippets supplied here ^{[1] [2]}. Ballotpedia and state-legislature trackers linked in the search results focus on state legislative composition rather than U.S. congressional delegations, so they don’t answer this congressional question directly ^{[3] [4]}.

5. Practical next steps to get a definitive answer

Use the full “List of current United States representatives” page to inspect every state’s House delegation and pair that with a current Senate roster; count whether any state’s two senators and its one-or-more House members are all non-Republicans. The Wikipedia roster referenced in the results is explicitly intended for that purpose ^[1]. Alternatively, consult the House Press Gallery’s member-data pages for downloadable breakdowns that may be sortable by state ^[2].

6. Competing perspectives and potential pitfalls

Different trackers may disagree on timing because of resignations, special elections, runoffs, or vacancies noted in the Wikipedia snippet—e.g., New Jersey’s 11th district special election and other runoffs or vacancies mentioned—so any list will be a snapshot that can change quickly ^[1]. Relying on aggregate delegation-control summaries risks missing states where a single vacancy or recent special election temporarily produces a one-party delegation; the Wikipedia snippet explicitly cites recent resignations and runoffs as reasons totals shift ^[1].

Limitations: This analysis uses only the supplied search excerpts; there is no single cited list among them that names states with no Republican congressional representation. To produce that precise list, consult the full roster pages cited above and cross-check current Senate membership ^{[1] [2]}.
