Competitive Races (Toss-up or Lean)

Alaska Toss-up
Dan Sullivan (R) - Incumbent, seeking third term; at about 42% in primary (certified), advancing to RCV general
Mary Peltola (D) - Former US Rep; led primary at about 49% (certified), advancing to RCV general; sole Democrat on ballot after Leslie withdrew
Dan J. Sullivan Jr. (R) - Retired teacher from Petersburg; name-sharing 3rd-place finisher (certified), advancing to RCV general
RCV tabulation pending. Updated first-choice count (394 of 401 precincts reporting, Nov 6-7): Peltola ~48.0%, Sullivan ~47.7% (gap has narrowed as more precincts came in; exact vote totals not confirmed by Division of Elections). Domestic absentee ballots accepted through Nov 13; international through Nov 18. Official RCV tabulation scheduled for Nov 18; certification expected by Nov 25. Next Division of Elections count update expected Nov 10 (expected to include almost all early votes and a large batch of absentee ballots). Peltola campaign filed lawsuit Nov 6 against Alaska election officials seeking information about rejected absentee ballots; Alaska Department of Law responded that the data is preliminary and treated as confidential. Trump DOJ pre-election lawsuit seeking to block Alaska Senate certification was dismissed by federal judge Nov 2; DOJ indicated intent to appeal on procedural grounds. Alaska Beacon preliminary analysis (using state data file) projects Sullivan nets ~860 more redistributed votes than Peltola from eliminated candidates (Heikes and Dan J. Sullivan Jr.), which could affect the outcome; Sullivan campaign hypothetical claims a 328-vote RCV win, treat as partisan projection. Prior count (Nov 4 morning, ~74.3% reported): Peltola led by ~626 votes (102,701 to 102,075). Election-night initial first-round: Sullivan ~48.5%, Peltola ~47.7%, Heikes (R) ~2.2%, Dan J. Sullivan Jr. (R) ~1.7% (all election-night counts, provisional). No AP call; state certification expected by Nov 25. Certified Sep 2: Ballot set for November. Peltola (D) and Sen. Sullivan (R, incumbent) clearly advanced with about 49% and 42% respectively. Dan J. Sullivan Jr. (R, name-sharing retired teacher from Petersburg) certified 3rd. David Leslie (D, democratic socialist) finished 4th but withdrew Sep 1 before the certification deadline, elevating Republican Gerald Heikes (R) to the 4th ballot spot. November RCV ballot: Sullivan (R), Peltola (D), Dan J. Sullivan Jr. (R), Heikes (R). DOJ grand jury probe into Dan J. Sullivan Jr.'s entry (potential voter confusion) remains ongoing. A New York Times report (published Sep 24) alleged hostile behavior by Peltola toward ex-staffers; Peltola campaign disputed the account and said she was grieving her husband's death during the period in question. Inside Elections moved from Tilt R to Toss-up on Oct 1, 2026 (Cook, Sabato, and Inside Elections all now rate Alaska Senate Toss-up). Sabato's Crystal Ball moved from Toss-up to Lean D on Oct 6, 2026 (Cook and Inside Elections remain Toss-up). Updated: Nov 8, 2026

Common Questions About the 2026 Senate Elections

When is the 2026 Senate election?

Election Day is Tuesday, November 3, 2026. Federal general elections are held on the first Tuesday after the first Monday in November. Many states also hold primaries earlier in the year and some hold runoffs afterward, so the date that matters for a given race depends on your state.

How many Senate seats are up in 2026?

35 seats: the 33 regular Class 2 seats, plus special elections in Ohio and Florida to fill vacancies. Republicans are defending 22 of them and Democrats 13.

Why are 35 seats up instead of 33?

Only 33 seats belong to Class 2, the group whose six-year terms expire in 2026. The other two are special elections, which are held when a seat becomes vacant between regular elections. Special elections can appear in any state in any cycle.

What is a Senate class?

The Senate is divided into three classes so that terms are staggered and roughly one third of the chamber is elected every two years. Each senator serves a six-year term. Class 2 seats were last contested in 2020, which is why they are on the ballot again in 2026.

How many seats does a party need to control the Senate?

51 of the 100 seats gives a party outright control. A party can also operate a majority with 50 seats if it holds the vice presidency, because the Vice President casts tie-breaking votes in the Senate.

When do the winners take office?

Newly elected senators are sworn in when the new Congress convenes on January 3, 2027, under the 20th Amendment. Winners of special elections may be seated earlier, since they are filling a seat that is already vacant.
