Everything you need to know about the 2024 US presidential election | US elections 2024

The 60th US presidential election will decide the 47th president – widely held to be the most powerful job in the world – and 50th vice-president. The candidates and their supporters are describing it as the most important election of their lifetimes with democracy and the American way of life are at stake. Record amounts of money have been raised and spent on campaign ads and ground games. Media coverage in print, on TV, online and on podcasts has never been more intense – or more polarised.

All 435 seats in the House of Representatives are up for grabs along with 34 of the 100 seats in the Senate, which together will decide the membership of the 119th Congress. Thirteen state and territorial governorships and numerous other state and local elections will take place.

Voters in 41 states will consider a total of 159 ballot initiatives. Ten states including Arizona, Colorado and Florida have abortion-related measures on the ballot. Florida, North Dakota and South Dakota are considering whether to legalise marijuana.

How are people voting?

It no longer makes sense to talk solely about “election day”. Tens of millions of people have voted early by mail or in-person, thereby avoiding long queues, potential bad weather or other inconveniences. Georgia’s first day of early voting “shattered records”, according to state officials, while an “unheard of” 97,000-plus voted on day one in Wisconsin.

Democrats encouraged people to vote by mail in 2020 to avoid exposure to Covid-19 during the pandemic and fought legal battles to expand absentee voting. Trump, by contrast, falsely claimed that the practice was rife with fraud (it is extremely rare), although Republicans have since changed their messaging and increasingly embraced it.

With the exception of Alabama, Mississippi and New Hampshire, all states give voters the chance to cast a ballot in person at a polling place ahead of election day, according to the National Conference of State Legislatures.

Most states begin counting those ballots on election day, and some require officials to wait until polls are closed to begin counting. Some states offer a version of early voting called “in-person absentee” voting, in which a voter can obtain and submit an absentee ballot in person at a polling place before election day.

Most states offer some form of absentee voting, in which a voter requests a ballot in advance and returns it by mail. Some offer voters the option of returning absentee ballots to a secure dropbox. Eight states practice “all-mail” elections in which all registered voters receive a ballot in the mail, whether or not they plan to use it.

Federal law requires states to send absentee ballots to military voters and voters overseas. Most states allow officials to immediately process absentee ballots but some require them to wait until election day to begin processing ballots – which can slow the release of election results.

On election day, which is 5 November this year, everyone else goes to polling places to cast their vote. Once ballots are tallied, results start being released.

Kamala Harris, 60, the current vice-president, won the Democratic party’s nomination after Joe Biden ended his re-election bid. She is a former senator, California attorney general and San Francisco prosecutor and is bidding to make history as the first woman and first woman of colour to be elected president in America’s 248-year history.

Donald Trump, 78, the Republican nominee, is making make his third consecutive run for the White House. The businessman and reality TV star continues to repeat his false claim that Democrats stole the 2020 election from him. He is the first president to be impeached twice and convicted of a crime. Trump is also the oldest major party nominee in history and this summer survived two assassination attempts.

Chase Oliver, 39, is the little-known candidate for the Libertarian party. Oliver ran for a Georgia state senate seat in 2022 and garnered 2% of the vote. The party, which prioritises small government and individual freedoms, typically gains 3% or less of the national vote but its members could yet prove crucial in swing states.

Jill Stein, 74, a physician who ran under the Green party in 2016, is running again in 2024. She launched her current campaign accusing Democrats of betraying their promises “for working people, youth and the climate again and again – while Republicans don’t even make such promises in the first place”.

Cornel West, 71, is running as an independent candidate. The political activist, philosopher and academic is making an effort to attract more progressive, Democratic-leaning voters.

What are the paths to victory?

Democrats have won the national popular vote in seven of the past eight presidential elections. But the Republicans George W Bush and Donald Trump won the White House by gaining more than 270 votes in the all-important electoral college.

Each state counts its votes separately. With two exceptions – Nebraska and Maine – the winner of a state gets all of its electoral votes. Each state has a number of electors based on the number of congressional districts it has, plus two additional votes representing the state’s Senate seats. Washington DC has three electoral votes, despite having no voting representation in Congress.

This year the electoral college will probably come down to seven crucial battleground states – Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin. The Harris and Trump campaigns are eyeing multiple combinations that could put them over the top.

Pennsylvania, which carries 19 electoral college votes, is the ultimate prize and has been the focus of much campaigning. Along with Michigan and Wisconsin, it forms a “blue wall” won by Barack Obama, lost by Hillary Clinton and won by Joe Biden. Trump is targeting rural blue-collar voters; Harris is aiming to turn out Black voters in big cities.

Losses in these states might be offset by victories in Arizona, where Trump has made gains among Latino voters; Nevada, the most diverse swing state; and Georgia, long a red state which Biden narrowly flipped in 2020. Republicans have won North Carolina in every election since 2012 but Democrats are running close this time.

Democrats currently control the Senate but face a tough map this year. Democrats and senators who caucus with them currently occupy seven of the eight most competitive seats, including Montana and Ohio, which generally lean Republican.

The House is likely to hinge on 42 of the most competitive elections. Republicans could retain control by winning just 12 of the 26 seats rated as toss-ups by the Cook Political Report if they also win seats deemed “likely” or “lean” Republican.

What are the main issues that will decide the White House?

Abortion. This is the first presidential election since the supreme court overturned Roe v Wade, the 1973 ruling that enshrined the constitutional right to abortion. Many Republican-led states have since imposed total or near-total bans on the procedure. Harris has made reproductive rights and personal freedoms a rallying cry and backs a national law codifying access to safe abortion. Trump has struggled to find his footing on the issue, insisting that it is a state matter and belatedly ruling out a national ban. Constitutional amendments that would protect or expand abortion rights will appear on the ballot in 10 states, which Democrats hope will drive higher turnout.

Democracy. Democrats have warned that Trump poses an existential threat to democratic norms, citing the 6 January 2021 insurrection, when a mob of his supporters attempted to overturn his election defeat. Harris has described her opponent as a fascist who has said he would be a dictator on day one and who would yield to foreign autocrats such as Vladimir Putin and Kim Jong-un. Trump has sought to turn the tables by claiming – without evidence – that Harris is the true threat to democracy, citing alleged online censorship and the criminal cases against him. He has refused to commit to accepting the results of the 2024 election. A recent a Washington Post-Schar School survey of voters in seven swing states found that slightly more trust Trump to handle threats to democracy than Harris.

Economy. The Economist magazine describes the US economy as the envy of the world, contending: “The American economy has left other rich countries in the dust.” But despite strong growth, low unemployment and stabilising inflation, Biden and Harris have consistently trailed Trump in opinion polls. Harris’s economic plans include tax cuts for most Americans, price-gouging bans, more affordable housing and a new child tax credit as well as efforts to boost domestic manufacturing. Trump has vowed to cut taxes, impose sweeping tariffs on imported goods and protect social security and Medicare.

Immigration. This has been Trump’s signature issue since he trundled down an escalator at Trump Tower in June 2015 to launch his presidential bid. This time, even as border crossings drop to 2020 levels, he has pledged what he calls the biggest deportation operation in US history. He has also used dehumanising language reminiscent of the Nazis to claim that undocumented immigrants are “animals”, have “bad genes” and are “poisoning the blood of our country”. Harris has shifted to the centre on the issue, underlining her support for a bipartisan proposal in Congress that would have hired thousands of new border security agents and closed the border if crossings hit an average of more than 5,000 people a day over a week.

What is the state of the race?

Excruciatingly close. Harris and Trump are tied at 48% each for the popular vote, according to the final New York Times/Siena College national poll published on 25 October.

After Joe Biden’s disastrous performance in the 27 June debate, Trump held a four-percentage-point lead over Biden among registered voters, according to the Pew Research Center. Biden dropped out and endorsed Harris, who then surged to parity and a small lead over Trump amid a wave of energy and enthusiasm.

In recent weeks the race has stabilised and an equilibrium has been restored.

The national race is less important than swing states that will decide the electoral college. These too are tantalisingly close. As of 17 October, for example, the Guardian’s poll tracker showed Trump narrowly leading in Arizona, Georgia, Michigan and Wisconsin, Harris ahead in Nevada and Pennsylvania and a dead heat in North Carolina – but all could still go one way or the other.

The election will provide another test for a polling industry battered by the 2016 and 2020 elections when it seemed to underestimate Trump’s strength. Conversely, in the 2022 midterms, Democrats overperformed the polls and headed off the predicted “red wave”.

Political analysts and commentators are understandably reluctant to stick out their necks and guess the outcome. Frank Luntz, a consultant and pollster, said: “You can’t call it. Anyone who calls it is an idiot.” But Allan Lichtman, a historian with a predictive method that has been right nine times out of 10, has declared he thinks Harris will win.

Does the US have exit polls?

Exit polls are surveys conducted with voters immediately after they have cast their ballots. Major news networks such as CNN, ABC and Fox News use them to make early projections about who is likely to win, though these are subject to revisions as actual vote counts come in. Traditionally, media outlets agree not to release exit poll data before all polls have closed to avoid influencing people still voting.

Exit pollsters position interviewers at selected polling stations, chosen to represent a cross-section of the voting population. Voters leaving polling stations are asked to voluntarily complete anonymous questionnaires covering the candidate they voted for, key issues and demographic information. Interviewers typically phone in the results three times during the day.

Exit poll data is analysed quickly to generate insights about the voter base such as who is winning certain demographic groups. Dearborn, Michigan, for example, will be studied closely for any evidence that the war in Gaza affected turnout of Arab and Muslim Americans.

Exit polls include absentee voters by conducting phone, text and email surveys. In states with a high level of early in-person voters, exit polls are carried out weeks before election day as these voters leave the polling place. The results are then combined with data from election day.

There is a strict embargo on exit poll data until 5pm ET on election day. Within the next hour some initial demographic information about voters and their policy views begins to emerge. Networks are not allowed to project a winner while voting is still taking place. The complete results are published after polling stations close in each state.

When will we know who won the election?

If the polls are wrong and one candidate has a clear lead over the other – think Ronald Reagan’s 49-state landslide victory in 1984 – the result will be obvious within hours. But given the closeness of the elections in 2016 and 2020, a nail-biter that runs through the night and possibly days beyond is more likely. Prolonged court cases are also possible: Republican donors and conservative billionaires have given $140m to 50 “election integrity” groups ready to do battle.

News organisations such the Associated Press (AP) often project a winner on election night based on an analysis of votes already counted, the number of outstanding votes and the margin between the candidates. (The AP says its accuracy rate for the past several general elections is above 99.9%.) The losing candidate typically concedes in the early hours of the next morning, signalling that the contest is in effect over.

Officially, however, there is still work to do. Local officials finish counting ballots in the days after the election and send their results to state officials. They approve the results and send them to federal officials. Every state must name individuals known as electors by 11 December; they must meet in their respective state capitols to cast their votes for president and vice-president on 17 December.

On 6 January the House and Senate will count and tally the electoral certificates in a joint session. The vice-president serves as the president of the Senate and formally presides over the receiving and counting of electoral ballots cast and announces the result. In this case, Harris will proclaim her own victory or defeat on the fourth anniversary of the insurrection at the US Capitol.

The election could be a big payday for lawyers. In 2000, when the Republican George W Bush and the Democrat Al Gore were the candidates, polling day fell on 7 November but the result was not called until 12 December. All eyes were on Florida, where votes were subject to an automatic recount because of Bush’s gossamer-thin margin of victory. The dispute went all the way to the supreme court, where justices voted to terminate the recount, prompting Gore to concede.

In 2020 the AP declared Joe Biden the winner four days after election day – at 11.26am ET on Saturday 7 November. Trump had declared victory three days earlier, even as more than 1m ballots remained uncounted, and went on to lose more than 60 legal challenges. Few would bet against him mounting a similar effort this time.

What happens after the race is decided?

The president-elect forms a transition team to plan for the transfer of power. This works on setting up policy priorities, vetting candidates for key administration positions and coordinating with the outgoing administration. The president-elect and key members of their team begin receiving classified national security briefings to prepare for handling ongoing or emerging global threats.

The 47th president will be inaugurated at 12 noon on 20 January at the US Capitol. Big crowds will be expected to return next year after Biden’s scaled-down pandemic version. The outgoing president typically attends the inauguration as a symbol of the peaceful transfer of power, although Trump boycotted in 2020. The new president begins work immediately, often signing a series of executive orders to reverse or continue certain policies and holding meetings with their team.
