Control of Congress hangs in the balance as Americans head to the polls in the 2026 midterms, but the timing of when a majority in the Senate and House will be known depends heavily on how quickly key states count ballots and how close the races prove to be. NBC News Decision Desk analysts outline scenarios that could see projections on election night or stretch into weeks.
Senate control hinges on eight battlegrounds
Senate majority will likely be decided by eight races rated as toss-ups or leaning Democratic: Alaska, Iowa, Kansas, Ohio, Texas, Maine, Michigan, and New Hampshire. Assuming Democrats hold seats rated likely Democratic, they still need to win five of these eight contests. Vote-counting speed varies significantly across these states.
Fast-counting states may yield early calls
Iowa, Kansas, Ohio, and Texas historically report over 80% of votes by midnight Eastern time. If recent polling spreads hold, some of these Senate races could be called before midnight. However, even if Democrats sweep all four, the Senate majority would remain undecided because five wins are required.
Steady counters: New Hampshire and Michigan
New Hampshire and Michigan count votes more gradually through election night into Wednesday morning due to decentralized, town-level administration. In Michigan, Wayne County often releases large vote batches between midnight and 3 a.m. ET, making early calls unlikely in close races. New Hampshire could potentially be called before midnight if Democratic momentum materializes.
Ranked-choice wild cards: Maine and Alaska
Maine and Alaska are the slowest counters. Maine's town-based system and Alaska's mail ballots arriving up to 15 days post-election mean close races may not be called on election night. Both states use ranked-choice voting for Senate; if no candidate exceeds 50% in first choices, tabulation occurs days later — 10 days in Maine, 15 days in Alaska. If Senate control depends on either seat, the majority could remain unknown for weeks.
House majority timing tied to size of majority
Democrats need a net gain of three seats to flip the House, and polling favors them. However, the size of the eventual majority determines projection speed. A single-digit majority for either party could take days or weeks to confirm, as seen in 2022 (eight days) and 2024 (until the second Wednesday). Ranked-choice voting in Maine's 2nd District and Alaska's at-large district adds similar delays if control hinges on those races.
Early bellwethers to watch
Kentucky's 6th District, closing at 6 p.m. ET and reporting quickly, offers an early indicator: a low-single-digit Republican win signals Democratic strength, while a Democratic win suggests a wave. Florida's fast-counting districts, including the 14th, 22nd, and 25th, may provide the first toss-up projections. If one party wins both Florida toss-ups early, that party could secure the majority.
