- Maine is the only genuine competitive Senate race in the Northeast — Susan Collins's approval has declined from 60%+ to around 52%, driven by 2025 votes confirming controversial Trump nominees and declining to break with her party on key procedural votes.
- New Hampshire's open seat (Shaheen retiring) is rated Lean D to Toss-up — without Kelly Ayotte, Democrats hold a structural edge, but the race will be decided by candidate quality among NH's large independent voter bloc.
- Connecticut's Chris Murphy and Rhode Island's Sheldon Whitehouse run in Safe D territory — neither faces meaningful Republican competition and both will focus on national policy influence rather than electoral defense.
- Delaware's Chris Coons holds Biden's former seat in one of the most Democratic states in the country; his re-election is effectively guaranteed regardless of the national environment.
- The Northeast's Senate map is overwhelmingly favorable to Democrats — Maine is the exception that proves the rule, and even there, Collins's personal brand has historically made her a structural outlier in a region that otherwise produces blowout Democratic margins.
Maine: The Northeast's Only Competitive Race
Susan Collins has won election and reelection to the Senate from Maine four times, consistently outrunning the Republican baseline by double digits through a carefully cultivated moderate, bipartisan image. That image has always been her greatest electoral asset. In 2020, Collins survived an unusually well-funded Democratic challenge by Sara Gideon, winning by 9 points despite national Republicans broadly underperforming. However, Collins's votes in 2025 — confirming several controversial Trump cabinet nominees and declining to break with Republicans on key procedural votes — have shaved her independent voters approval. Her approval in recent Maine polls stands at approximately 52%, down from 60%+ in prior cycles. She remains favored but is genuinely competitive for the first time since 2020.
Maine's unique political geography complicates the picture. The state awards electoral votes by congressional district, and its two congressional districts voted differently in 2024 (ME-1 Biden, ME-2 Trump). Collins has traditionally performed well in both urban Portland and rural northern Maine. Democrats are targeting the race seriously and have recruited a candidate who can compete in both regions. The RCV system means voters can rank candidates; in a world where an independent candidate draws significant protest votes from Collins's right, RCV could advantage a Democratic challenger consolidating progressive support.
Delaware: Coons Runs in Biden's Home State
Chris Coons, who holds the Senate majority math Joe Biden held for 36 years, is running for reelection in a D+18 state with strong name recognition and a moderate bipartisan profile. Delaware has not elected a Republican to statewide office in over two decades. Republicans are unlikely to recruit a credible challenger in a seat this uncompetitive. The NRSC is not targeting Delaware. Coons is spending the 2026 cycle focusing on national fundraising for competitive races and building his profile ahead of a potential 2028 presidential race consideration.
Connecticut and Rhode Island: Murphy and Whitehouse Safe
Chris Murphy (Connecticut) has built a national profile on gun violence prevention and foreign policy, particularly on NATO and Ukraine. His approval in Connecticut remains high, and the state is deeply Democratic. Murphy is raising money for 2026 Senate colleagues rather than for his own competitive race. Sheldon Whitehouse (Rhode Island) is an incumbent in the most Democratic state in the country by presidential performance. His work on environmental law and dark money has generated some national controversy but no genuine electoral threat at home. Both senators are Safe D. The Northeast, in short, contributes three guaranteed Democratic holds and one competitive but Republican-leaning race in Maine to the 2026 Senate map.
Frequently Asked Questions
Is Susan Collins vulnerable in Maine in 2026?
Collins is competitive but favored (Lean R). Her approval is down from prior cycles due to 2025 Trump votes. She outperforms the Republican baseline by ~15 points historically, but a D+6 state with an engaged opposition base makes this a real race. Democrats are recruiting a strong challenger.
Which Northeast Senate seats are safe for Democrats?
Delaware (Coons), Rhode Island (Whitehouse), and Connecticut (Murphy) are all Safe D. No competitive Republican challengers are expected in any of the three states.
Does Maine use ranked choice voting for Senate races?
Yes. Maine uses RCV for federal elections since 2018. In a competitive 2026 Senate race, RCV could influence outcomes if independent candidates draw significant vote share. It generally advantages the candidate with broader coalition support.
