When will we know who’s won the US midterm elections?
asserted
who → know → elections
The contest for control of Congress represents the biggest political test yet of US President Donald Trump’s second term.
asserted
contest → represent → term
The results of each race in the US House of Representatives and the Senate – along with the thousands of other races taking place at the state and local level – could take anywhere from minutes to weeks to become clear.
uncertain
results → take → weeks
Administration of elections in the US is decentralised; 50 different state laws govern the contests, and some states further delegate key functions to counties.
asserted
states → decentralise → counties
But within hours of polls closing, race calls in a few competitive House contests in East Coast states are likely to show whether the “blue wave” of Democratic wins that forecasters expected is materialising.
asserted
forecasters → close → wins
Exactly how high that wave will crest – and which party gets control of the Senate – will depend on races that will be called later.
asserted
that → crest → races
And there’s a danger that early data could provide a misleading “mirage.”
uncertain
data → ’ → mirage
Democrats need a net gain of just three seats to take control of the House, and four for the Senate.
asserted
Democrats → need → Senate
Winning the House is enough to block legislation backed by Trump and bog him down in oversight investigations – and, potentially, impeachment.
asserted
Winning → win → investigations
Winning the Senate would also give Democrats veto power over the president’s high-level executive and judicial appointments.
asserted
Winning → win → appointments
When do the polls close on Nov 3?
Each state sets its own polling times.
asserted
state → close → times
The first polls are scheduled to close in Kentucky and Indiana at 6pm New York time (7am Singapore time on Nov 4).
asserted
polls → schedule → Nov
The final precincts – including Adak Island, Alaska, the westernmost polling place in the US – are set to close at 1am New York time on Nov 4.
asserted
precincts → include → Nov
Voters will be allowed to vote as long as they are in line as of closing time.
And all of these times could be extended by court order under certain circumstances – for example, if specific polling places were inaccessible early in the day.
uncertain
places → allow → day
Such exigencies could delay results.
When do states start reporting results?
uncertain
states → delay → results
Most states can start reporting their running counts within minutes after polls close, but there are local complexities.
asserted
polls → start → minutes
In Kentucky and Indiana, for example, counties in the Eastern time zone will start reporting vote counts even while voters in the Central time zone are still casting ballots.
Other states, including Alabama, Alaska, Oregon and South Dakota, typically hold off on reporting any results until all counties have voted.
asserted
counties → start → results
And in Arizona and Idaho, state laws require officials to wait an hour after polls have closed before reporting any results.
asserted
polls → require → results
How long will it take to determine who’s won?
If the last midterm election in 2022 is any indication, it could take days.
uncertain
it → take → days
That year, the Associated Press didn’t call control of the House until Nov 16 – eight days after the election.
asserted
Press → call → election
Representative Mike Garcia’s reelection in a California district gave Republicans their 218th seat and a majority.
asserted
reelection → give → seat
If it’s a close election in 2026, it will likely come down to California again.
asserted
it → ’ → California
Its mail-in voting system allows ballots postmarked by Election Day to be counted even if they’re not delivered until seven days later.
asserted
they → mail → Day
If Democrats win key early House races, the writing could be on the wall long before the 218th race is called.
uncertain
race → win → wall
One such race is in Kentucky’s 6th District, a district Trump won by 15 points but where Democrat Zach Dembo is challenging Republican Ralph Alvarado in a surprisingly close race that the election analysis service Cook Political Report rates as a toss-up.
asserted
service → win → up
One potential holdup is Alaska, which uses ranked-choice voting to determine the winner.
asserted
which → use → winner
Voters choose their favourite candidate but can also select a second-favorite, a third and so on.
asserted
Voters → choose → favorite
If no candidate gets a majority of first-place votes, the candidate with the fewest first-choice votes is eliminated.
asserted
candidate → get → votes
Those voters’ ballots are then reassigned to their second choice.
asserted
ballots → reassign → choice
The process repeats until someone secures a majority.
asserted
someone → repeat → majority
But that process can’t happen until Nov 18, after all mail-in ballots are received.
asserted
ballots → happen → Nov
Why does it take so long to determine a winner?
Some votes require additional processing time.
asserted
votes → take → time
These include:
Provisional ballots.
asserted
These → include → ballots
A provisional ballot is cast by a voter when there’s some question about the validity of their vote on Election Day.
asserted
ballot → cast → Day
It often requires more investigation about the voter’s registration status or precinct.
asserted
It → require → status
In June, the Supreme Court settled a contentious issue at the heart of several recent election disputes: Whether states can count ballots postmarked by Election Day but received afterward.
asserted
states → settle → Day
They can, the court ruled in a 5-4 decision.
asserted
court → rule → decision
Fifteen states allow that grace period, but they have different deadlines and procedures for counting them.
asserted
they → allow → them
Some states allow voters to “cure” those ballots after the fact, which can take time.
asserted
which → allow → time
Election officials also need to verify that the voter hasn’t also cast a ballot in person.
asserted
voter → need → person
…and 41 more, not listed.
