Why Some Election Races Take Days or Weeks to Call

Reading

On election night, television maps fill with color within hours, so it can look as if the vote has been counted. It has not. What viewers see is mostly a series of race calls: a news organization’s projection that one candidate cannot be caught. No state finishes its official count on election night, and in close races the gap between the night’s headlines and the final result can last weeks. The reasons are mostly written into state law.

Mail Ballots Take Extra Steps

An in-person vote is usually scanned the moment the voter feeds it into a machine. An absentee ballot sent by mail needs processing first: logging its arrival, checking the envelope, comparing the voter’s signature with the one on file (signature verification), opening the envelope and flattening the ballot. Only then comes tabulation, when scanners count the votes. Forty-four states let officials begin processing before Election Day, but six, including Pennsylvania and Wisconsin, do not allow it until Election Day itself, according to the National Conference of State Legislatures (NCSL). In those states, large piles of mail ballots are still being opened while polls close.

Timing also depends on when ballots may arrive. Some states count only ballots received by Election Day. Others have a grace period for ballots with a postmark on or before Election Day. In June 2026 the Supreme Court ruled that federal law allows such grace periods (see our coverage of the ruling). Ballots from overseas and military voters often have separate, later deadlines too. In Alaska, qualifying absentee ballots can arrive up to 15 days after the election, PBS NewsHour reported.

Fixing Problems Before Ballots Count

Some ballots arrive with a missing signature or one that does not match. In 33 states, voters are told about the problem and given a chance to cure it, NCSL reports. Deadlines vary: Nevada allows six days after the election, and Arizona allows five business days. Voters whose eligibility is uncertain on Election Day may cast a provisional ballot, which counts only after officials confirm the voter was entitled to vote. Until those deadlines pass, a few thousand ballots in a close race remain undecided.

Counting in Batches, Then Making It Official

Counties report results in batches as they finish them, which is why leads can shift overnight when a large county reports its mail ballots late. After counting comes the canvass, when local boards check totals against records, and then certification, when officials formally approve the results. Certification deadlines range widely: some local results are certified within days, while Ohio’s canvass is not final until 81 days after the election and California certifies statewide results on day 38.

Recounts, Ranked Choice and Runoffs

A very close result can trigger a recount. Twenty-eight states have automatic recounts when the margin falls below a legal threshold, often half a percentage point, and 43 allow candidates or voters to request one, according to Ballotpedia. Recounts add weeks but rarely change the winner: of 36 statewide recounts from 2000 to 2023, three reversed the result, and the average shift was about 551 votes, a FairVote analysis found.

Two states add a further step. Maine and Alaska use ranked choice voting, so if no candidate wins a majority of first choices, ballots are counted again in rounds (see our ranked choice explainer). Maine must bring ballots and memory devices to the capital, Augusta, for that count. Georgia goes further still: a candidate who fails to win more than 50% faces a runoff election about four weeks later, on Dec. 1 this year.

Who Calls a Race, and Why It Matters

Race calls come from news organizations such as The Associated Press and Decision Desk HQ, not from governments. A call is a statistical judgment that the trailing candidate cannot catch up based on the votes still outstanding. Calls are usually right, but they are not official, and a concession speech has no legal force either.

The length of the count has become politically contested. President Trump and the Republican National Committee argue that results should be known on election night and that ballots arriving after Election Day should not count. Election administrators answer that counting speed reflects state law and that accuracy matters more than speed. Data from the 2024 election suggests the stakes of the late-ballot fight are modest: late-arriving ballots made up no more than about 3% of the vote in any state, Votebeat found. Whether a faster count would build trust or simply exclude some legitimate voters is the core disagreement.
