- Trump has struggled to find a consistent message in recent weeks.
American voters will face a clear choice for president on election day, between Democratic Vice-President Kamala Harris and Republican Donald Trump.
Here's a look at what they stand for and how their policies compare on eight key issues.
Economy
Harris has said her day-one priority would be trying to reduce food and housing costs for working families.
She promises to ban price-gouging on groceries, help first-time home buyers and provide incentives to increase housing supply.
Trump has promised to “end inflation”.
He wants to build more homes, and he says deporting undocumented immigrants will ease pressure on housing.
Abortion
Harris has made abortion rights central to her campaign, and she continues to advocate for legislation that would enshrine reproductive rights nationwide.
Trump has struggled to find a consistent message in recent weeks.
The three judges he appointed to the Supreme Court while president were pivotal in overturning the constitutional right to an abortion, a law known as Roe v Wade.
Immigration
Harris was tasked with tackling the root causes of the southern border crisis when she was vice-president. Record numbers of people crossed from Mexico at the end of 2023 but the numbers have fallen since.
In this campaign, she has toughened her language and emphasised her experience as a prosecutor in California taking on human traffickers.
Trump has made immigration one of his top campaign issues. He has vowed to seal the border with Mexico by completing the construction of a wall and increasing enforcement.
The former president has also promised the biggest mass deportations of undocumented migrants in US history.
Taxes
Harris says she wants to ease the tax burden, and has unveiled a number of measures including an expansion of child tax credits.
She says additional taxes on Americans making $400,000 (£305,000) a year and on big corporations will help pay for this.
Trump proposes a number of tax cuts worth trillions, including an extension of his 2017 cuts which mostly helped the wealthy. He says he will pay for them through higher growth and tariffs on imports.
Analysts say both tax plans will add to the ballooning deficit, but Trump’s by more.
Foreign policy
Harris has vowed to support Ukraine “for as long as it takes”. She has pledged, if elected, to ensure the US and not China wins "the competition for the 21st Century".
She has been a longtime advocate for a two-state solution between the Israelis and Palestinians, and has called for an end to the war in Gaza.
Trump has an isolationist foreign policy and wants the US to disentangle itself from conflicts elsewhere in the world.
He has said he would end the war in Ukraine in 24 hours through a negotiated settlement with Russia, a move that Democrats say would embolden Vladimir Putin.
Trump has positioned himself as a staunch supporter of Israel but said little on how he would end the war in Gaza.
Trade
Harris has criticised Trump’s sweeping plan to put tariffs on imports, calling it a national tax on working families which will cost each household $4,000 a year. She is expected to have a more targeted approach to taxing imports.
Trump has made tariffs a central pledge in this campaign. He has proposed new 10-20% tariffs on most foreign goods, and much higher ones on those from China.
Climate
Harris, as vice-president, helped pass the Inflation Reduction Act, which has funnelled hundreds of billions of dollars to renewable energy, and electric vehicle tax credit and rebate programmes.
But she has dropped her opposition to fracking, a technique for recovering gas and oil opposed by environmentalists.
Trump, while in the White House, rolled back hundreds of environmental protections, including limits on carbon dioxide emissions from power plants and vehicles.
In this campaign he has vowed to expand Arctic drilling and attacked electric cars.
Healthcare
Harris has been part of a White House administration which has reduced prescription drug costs and capped insulin prices at $35.
Trump has said he will not renew his attempts while president to dismantle the Affordable Care Act, which extended insurance to millions more people.
He has called for taxpayer-funded fertility treatment, but that could be opposed by Republicans in Congress.
Crime
Harris has tried to contrast her experience as a prosecutor with the fact Trump has been convicted of a crime.
He became the first former president to become a felon over a scheme to influence the 2016 election by covering up a hush-money payment.
Trump has vowed to demolish drugs cartels, crush gang violence and rebuild Democratic-run cities that he says are overrun with crime.
