How many Republican senators from New England are serving in the 2024 Congress?

1. The short answer: one Republican senator in New England

Every reliable roster cited in the compiled reporting identifies Maine’s Susan Collins as the only Republican senator representing any New England state in the current Senate delegation; the rest of the region’s Senate delegation comprises Democrats and two Independents who caucus with Democrats ^{[1] [2] [3]}.

2. Why that single-figure matters politically

New England’s Senate representation is heavily Democratic in the 119th Congress: nine Democrats, two Independents who caucus with Democrats, and one Republican (Collins). That distribution matters for regional influence on judiciary confirmations, appropriations and committee chair assignments because party alignment determines committee majorities and agenda control at the federal level ^{[2] [3]}.

3. Who is the Republican and what the sources say about her role

Susan Collins is identified repeatedly as Maine’s Republican senator and is singled out in reporting as “the only New England Republican” in recent Congresses, a status noted both in biographical profiles and region-wide summaries ^{[1] [4]}. Collins’ longevity and committee positions are emphasized in her profile, underscoring that the region’s sole GOP presence is a senior, influential figure ^[1].

4. How the rest of New England’s Senate delegation breaks down

The same sources enumerate the remainder of New England’s delegation as predominantly Democratic, with two Independents — Angus King (Maine) and Bernie Sanders (Vermont) — who caucus with Democrats, effectively increasing the Democratic-aligned caucus strength from the region ^{[2] [3]}. State-level pages and lists confirm New England’s tilt toward Democrats in the Senate ^{[3] [2]}.

5. Historical context: a long regional shift toward Democrats

Contemporary summaries and analyses trace New England’s political realignment: where the region once sent more Republicans to Congress, today only one Republican holds a Senate seat from New England ^{[4] [3]}. NPR’s reporting framed this as a marked change over recent decades, with Susan Collins noted as the region’s remaining Republican in federal office at the time of that reporting ^[4].

6. What the sourced records do not address

Available sources in the set do not provide a state-by-state listing of every current senator by party within this query package beyond the general totals and specific mentions of Collins and the two Independents; for a complete, state-level roster of sitting senators with party labels you would consult the official Senate directory or an updated list of current senators (not found in current reporting) ^{[5] [2]}.

7. Competing interpretations and why they matter

Some readers might infer that “New England has one Republican in Congress” means in the entire congressional delegation (House + Senate). The sources here focus on the Senate and regional summaries; NPR and Wikipedia-style summaries have both used similar language to highlight that only Collins remains among senators or the broader delegation in earlier years, so careful reading is required to distinguish House vs. Senate representation ^{[4] [3]}.

Limitations and sourcing note: this piece relies solely on the provided sources. For an up-to-the-minute, state-by-state roll call of party affiliation in the Senate consult the official Senate directory or Congress.gov; the materials supplied here identify Susan Collins as the lone Republican senator from New England and characterize the region’s remaining senators as Democrats or Democratic-caucusing Independents ^{[1] [2] [3]}.
