The 2026 Midterms, Nationwide

November 3, 2026 — control of the U.S. Senate and U.S. House

What's at stake: Voters pick all 435 U.S. House seats, 35 U.S. Senate seats, and 27 governorships*, but the national story is Congress. Senate: Republicans currently hold 53 seats to 47 for Democrats — Democrats need a net gain of four to take the majority. House: Republicans hold a narrow edge (about 218–212, with a few vacancies), so Democrats need a net gain of six to reclaim the speaker's gavel. (*Gov. note: 26 states hold races in addition to California.) Because 23 of the 35 Senate seats being contested are in states Donald Trump won in 2024, the Senate map is hostile to Democrats — but the House is widely rated as Democrats' best chance.

U.S. Senate — The Nine Races Most Likely to Decide Control

Ratings follow the Cook Political Report as of September 2026. Republicans are favored overall, but Democrats have credible pickup paths in NC, ME, MI, and OH.

StateTypeMatchupRatingNotes
North Carolina R open Roy Cooper (D) vs. Michael Whatley (R) Lean D Democrats' best pickup. Tillis retiring; ex-Gov. Cooper led every mid-2026 poll and outraised Whatley heavily.
Maine R held Susan Collins (R, inc) vs. Troy Jackson (D) Toss-up Collins's toughest race yet; Jackson is the former president of the Maine Senate. Only R-held seat in a Harris-won state.
Michigan D open Abdul El-Sayed (D) vs. Mike Rogers (R) Toss-up Peters retiring. GOP's best shot at a Dem seat. El-Sayed won a bitter progressive-backed primary; slight Dem favorite in polling.
Ohio R special Jon Husted (R, appt.) vs. Sherrod Brown (D) Toss-up Full-term race for Vance's old seat. Ex-Sen. Brown vs. appointee Husted; Brown has the cash edge (about $16M COH).
Georgia D held Jon Ossoff (D, inc) vs. Mike Collins (R) Lean D Ossoff favored with a huge war chest, but GA is a top-tier battleground and Collins has Trump's endorsement.
Iowa R open Ashley Hinson (R) vs. Josh Turek (D) Lean R Ernst retiring. Trade-policy discontent among farmers has made it more competitive than usual; Turek outraised expectations.
New Hampshire R open Chris Pappas (D) vs. John E. Sununu (R) Lean D Open seat after Shaheen retirement. Pappas & Sununu both won big Sept 8 primaries; a classic NH swing race.
Texas R open Ken Paxton (R) vs. James Talarico (D) Lean R Cornyn retiring. Talarico set a Q2 fundraising record and outraised Paxton by $26M; best Texas Senate chance in 30 yrs, still an uphill R state.
Alaska R held Dan Sullivan (R, inc) vs. Mary Peltola (D) Lean R Peltola won statewide as the House member; ranked-choice election with a look-alike decoy "Dan J. Sullivan" also on the ballot.

Also worth a glance: Florida (R-incumbent Ashley Moody favored over progressive Angie Nixon) and Nebraska (R-incumbent Pete Ricketts facing independent Dan Osborn). The likeliest Senate outcome per mid-2026 Cook analysis: Democrats net 1–3 seats — short of the 4 they need.

U.S. House — The Path to 218

All 435 seats are up. Raters see Democrats as slight favorites to flip the chamber.

Route to the MajorityWhat to watchRace impact
National environment A sour national mood, trade-policy fallout, and court fights have Democrats outperforming in special elections and generic-ballot polls through 2026. Sets the wind behind all California races.
California battlegrounds California holds several of the nation's most competitive seats. The marquee: CA-48 (Desmond vs. von Wilpert, covered on this site) — a genuine Toss-up where DCCC leaders concede the majority may run through it. CA-31 (safe D) and CA-40 (R-on-R, safe R) are not swing seats. CA-48 alone could be the deciding seat for a 218-seat majority.
Other swing states New York (several GOP-held metro seats), New Jersey (a handful), plus Phoenix/Tucson-area AZ and Las Vegas/Henderson NV races will decide the margin. NY/NJ suburban seats are Democrats' biggest pickup pool outside CA.
Special-election math A handful of vacancies (currently ~4) get filled in-season; every seat counts toward the 218 threshold. Keeps the threshold math tight through Election Day.

The California X-factor: After the June 2026 Prop 50 redistricting redraw, several Southern California districts became more competitive — most importantly the new-leaning-Democratic CA-48, while CA-40 consolidated two GOP incumbents into one safe Republican seat. Democrats' national path essentially requires holding all their swing seats and sweeping races like CA-48.

Bottom line: Expect a divided Washington. The House is genuinely in play (Democrats favored); the Senate is a reach for Democrats (net +4 needed on a brutal map). California's contribution to the story runs through the statewide races covered on this site, the 14 ballot measures, and the CA-48 Toss-up — the single most important district race in the state.
