US midterm election results hinge on state vote counting timelines
The outcome of the 2024 US midterm elections depends on when and how ballots are counted across states, with key races potentially taking days or weeks to resolve due to varying mail-in voting rules and processing times.
Polls begin closing on Tuesday evening, with the first results expected from parts of Indiana and Kentucky at 23:00 GMT. Voting ends sequentially from East to West, with all 435 House seats and 35 Senate seats up for grabs. Final results for control of Congress will be delayed as states follow their own counting procedures and deadlines.
Polls close across the United States over a seven-hour period, from 6pm Eastern Standard Time to 1am EST the following morning.

Vote counting rules by state
States vary in when and how ballots are counted, with mail-in ballot deadlines and signature verification processes affecting when results become available. No state is required to complete the official count on election night. State laws set deadlines to certify final results, often weeks later. Control of the U.S. Senate could come down to a handful of close races with large numbers of ballots to count.
California carries out elections primarily by mail. Large batches of ballots are verified days after polls close, so close House races can take days or weeks to resolve. Counties must count and report results from most ballots by the 13th day after the election, with some exceptions taking up to 30 days. When thousands of voters procrastinate sending in their mail ballots until the last minute, it takes election workers extra time.
All registered voters in Nevada are mailed ballots. Mail-in ballots postmarked by Election Day can arrive up to four days later, and voters have six days to fix signature problems, potentially delaying results until the following week. In some Arizona counties, mail-in ballots dropped off on Election Day must undergo signature checks, delaying results by several days in close races.
Alaska and Maine use ranked-choice voting. If no candidate receives more than 50 percent, extra rounds of counting are needed. In Alaska, mail-in voting results are released in the following days. If the US Senate race there requires ranked-choice tabulation, the next round is scheduled for November 18. Washington holds elections by mail, with ballots postmarked by Election Day counted in the following days.
Fast and slow reporting states
Some states often complete the majority of their unofficial counts faster than others. In the 2024 general election, about 99 percent of Florida votes were counted by 10:51pm EST. Ohio tends to release all or almost all early and absentee voting results first; by 11:03pm EST, 90 percent of results had been reported. North Carolina reached 90 percent of vote reporting at 11:36pm EST in 2024.
Other major states take longer. In 2024, Pennsylvania had half of votes reported by 10:12pm EST, rising to 90 percent by 12:48am EST the next day. Wisconsin saw 90 percent of results released by 2:22am on November 6. The pattern of when votes are counted, and what political leanings those jurisdictions' voters tend to have, varies by state.
In 2020, Donald Trump was up by more than 100,000 votes in Wisconsin early in the night, but the picture quickly shifted after Milwaukee's central count finished processing mail-in votes around 3:30 a.m local time. The winner of a key U.S. Senate race may not be clear until officials can count nearly all of Detroit's ballots. Detroit election officials predict they will report results for approximately 95% of ballots on election night, an estimate not a guarantee. As of late October, about half of the 106,000 absent voter ballots in Detroit had been returned.
Legal processes and misinformation
If a race is very close, a recount might be triggered automatically or if requested by a candidate, depending on state law. Candidates also have the option of challenging the results in court, which could delay the final result. Under the U.S. Constitution, the House and Senate have the final authority to judge disputes over the elections of their own members. The US president cannot overturn congressional election results simply because he disagrees with them.
In past elections, elected leaders, candidates and social media users have spread falsehoods that 'late night' arrivals of 'ballot dumps' are signs of fraud. Some have pointed to vans with ballots arriving late at night as evidence of foul play. What is fast or slow is how quickly the media can collect sufficient evidence to confidently predict the winner, which is typically based on the margin of victory. Mali Smith noted, "All the states run elections. Courts accept that states run elections."
The U.S. Supreme Court in June upheld the right of states to have policies allowing ballots postmarked by Election Day to arrive later, a blow to Trump, who says he wants a faster process. Ohio passed a law in 2025 that said most absentee ballots must be received by the close of polls on Election Day, removing a previous four-day grace period. Donald Trump said, "I will if there are honest elections," regarding respecting the final outcome. In 2024, it took eight days to determine which party would control the House of Representatives.
