Senate Control: Seven states and ranked-choice voting delay final results
Tight margins and complex counting rules mean Senate outcomes may remain uncertain for days, even as House results emerge faster.
By Marta Gray ·
The 2026 midterms present a complex path to chamber control, with Senate races expected to take longer than House contests to resolve.
Analysts attribute the delay to seven highly competitive Senate states and the use of ranked-choice voting in two of them. These factors extend the counting process beyond the initial poll closures on Tuesday night. The House, featuring larger margins, is likely to see its outcome determined sooner. However, the Senate race may hinge on a single seat, making the extended timeline a critical factor in determining the balance of power in the upper chamber.
Polls close in staggered waves starting at 7 p.m. Eastern Time, with Georgia, Indiana, Kentucky, South Carolina, Virginia, and Vermont reporting first. Georgia draws attention due to a tight gubernatorial race between Rick Jackson and Keisha Lance Bottoms. Secretary of State Brad Raffensperger noted that new laws require counties to report results within an hour of polls closing, a change from previous delays. In South Carolina, the Senate race between Darline Graham and Annie Andrews is described as unexpectedly tight, with national polls showing a toss-up despite the state's Republican lean.
By 8 p.m. Eastern Time, more than half the country will have closed polls. Key races include the Ohio Senate contest between Jon Husted and Sherrod Brown, which is currently deadlocked. Ohio has shifted from a swing state to a solidly Republican area in recent years, making the close race a focal point. In Florida, Governor Byron Donalds holds a slight lead in polls against David Jolly. The state's redistricted House maps will face their first test, with Cook Political Report identifying seven competitive House seats, two of which are toss-ups.
The final major wave of poll closures occurs at 9 p.m. Eastern Time, covering states including Arizona, Texas, and Michigan. In Texas, Democrat James Talarico faces Republican Ken Paxton in the governor's race, a contest where no Democrat has won statewide since the early 1990s. Early voting data may give Talarico an initial lead, but Paxton is expected to gain ground as county totals are reported. In Michigan, the race between Abdul El-Sayed and Mike Rogers remains a toss-up, with both candidates employing distinct campaign strategies that will determine the final outcome.
Ranked-choice voting in two states will further prolong the count. The specific mechanics of this system require additional time to tally preferences, meaning some Senate seats may remain undecided well into Wednesday. This procedural detail ensures that even if polling data suggests a clear favorite in certain districts, the official certification of results will depend on the full completion of the multi-round counting process.
