Election Day is Tuesday, November 3, 2026, and voting is underway in Idaho. This is the whole race — the records, the claims, and what the sources actually show. Read the research, and decide which flaw you can live with.
The setup Rep. Mike Simpson (R), in the House since 1999 — one of the longest-serving members of Congress — seeks another term. He won the Republican primary with 63.3% (63,448) over educator Brian Keene (20.9%) and brand manager Perry Shumway (15.8%). Simpson was re-elected with 61.4% in 2024, and Cook and Inside Elections both rate the seat Solid R. No Cook PVI figure was retrieved for this district in our research, so we print none; the lean rests on the 2024 margin and the Solid R ratings. Six candidates are on the ballot — the fullest field in this Idaho file: Simpson (R), Elinor "Ellie" Gilbreath (D), Will Johanson (Libertarian), Carta Sierra Peterson (Constitution), Emre Houser (Independent), and Tripp Hutchinson (Independent). Gilbreath won the Democratic primary with 72.5% (19,525). Two name notes, printed rather than resolved: the Democrat's formal first name is Elinor; she campaigns as Ellie Gilbreath — same person. The Constitution candidate appears as "Carta Sierra" in the FEC table and "Carta Sierra Peterson" in the results table. The latest located poll (VoteNexus Research, Oct. 21–22, 2026; methodology not assessed): Simpson 46%, Gilbreath 31%, others 12%, undecided 12%. Money (FEC as of June 30, 2026, via Wikipedia): Simpson raised $1,118,093 with $429,359 on hand, against Gilbreath's $106,892. Sourcing strength is compilation-level: Wikipedia cross-checked against AP primary reporting and a Daily Letter guide built from the Secretary of State's list, which was not directly retrieved this pass. A stale old-cycle "official list" reproduced in a university library guide was found and rejected in the research — it is not used.
Mike Simpson (R) The record: Simpson has served since 1999 — 14 terms — and was a dentist from Blackfoot before Congress (general biography, compilation strength). He is a senior appropriator, long associated with the Appropriations Committee and the Interior / Environment portfolio, and the longtime champion of the Idaho National Laboratory in appropriations (general record, compilation strength — current-cycle subcommittee assignments were not pulled, and we say so). He is endorsed for 2026 by President Trump, and also by AIPAC and Log Cabin Republicans (Wikipedia endorsements section). Campaign-conduct item, printed at its weight: he declined the League of Women Voters' forum invitation; his spokesperson cited his congressional schedule (Idaho Statesman via compilation, Oct. 2026). Pros: Institutional weight is a district asset and Simpson's is Idaho's largest: 27 years of seniority, the appropriations seat, and the INL file — the district's largest economic engine has had its champion in the room where the money moves for a generation. A 61.4% re-election and a 63.3% primary say the district knows exactly what it is keeping. Cons: The same seniority is the con's raw material: a member since 1999 is the institution his party's voters periodically rebel against, his primary opponents took a combined 36.7%, and like his colleague in ID-01 he declined a voters' forum — at his tenure, the schedule explanation wears thinner than the biography. The flaw, plainly: No conduct flaw, no integrity file, and no unclosed math was located. The priced item is tenure itself — 14 terms is a fact voters own, not a defect we manufacture — plus the forum refusal, recorded at the same modest weight as in ID-01.
Elinor "Ellie" Gilbreath (D) The record: Gilbreath is an attorney (Critical Report primary compilation) who won the Democratic primary with 72.5% over counselor Julie Wiley. Her located campaign themes, from commentary coverage: agriculture harm from the Iran war and from funding cuts in the 2025 reconciliation law — the source's partisan label for that law is its own wording and is not repeated as fact here; the underlying claim is that Simpson supported the law's cuts, and the roll call itself was not pulled this pass, so the claim prints as her campaign's, attributed. No prior elected office was located. Pros: A professional challenger who consolidated her primary at 72.5% and polls at 31% — the strongest Democratic number in either Idaho district. Cons: No office, no record, a ten-to-one money gap, and a campaign case built on a vote attribution our research could not independently pull. The flaw, plainly: Unproven, with no exception file — no service record exists from which a Manchin-test break could be documented.
Will Johanson (Libertarian), Carta Sierra Peterson (Constitution), Emre Houser (Independent), and Tripp Hutchinson (Independent) No record was located for any of the four beyond ballot qualification and FEC entries ($0 for Johanson, Sierra Peterson, and Houser; Hutchinson raised $7,565 as of June 30, 2026). In the located poll, Houser and Hutchinson combined for 5% and Johanson took 2%.
OUR CALL LiberalMind endorses Mike Simpson.
Twenty-seven years of in-tent service, the appropriations seniority that funds the district's signature institution, a fresh presidential endorsement, and no located flaw of a priced species — against an attorney challenger with no record and a campaign claim our research prints as attributed because the roll call was not pulled. The Manchin exception cannot be built on an empty file, and incumbency this long is a question Idaho's 2nd District has answered fourteen times.
The watch item for the next cycle is the one in the cons: a 63.3% primary against two little-known challengers is the softest number in Simpson's recent file, and entitlement is how long careers end. It is a watch item, not this year's verdict.
