While much focus has been placed on the personalities of Donald Trump and Hillary Clinton, there are many key issues that are important factors for voters in deciding who they want for US president on 8 November, ranging from abortion to taxes. Here are the candidates' stance on some of those issues:
Donald Trump’s stance on abortion has evolved over time and he has most recently said he is "totally against abortion".
Hillary Clinton is pro-choice and has said "abortion should remain legal, but it needs to be safe and rare".
Mrs Clinton has vowed to set "bold, national goals" from day one of her presidency regarding climate change.
She wants to make America "the world’s clean energy superpower and create millions of good-paying jobs, taking bold steps to slash carbon pollution at home and around the world, and ensuring no Americans are left out or left behind as we rapidly build a clean energy economy."
Mr Trump has been a sceptic of global warming for years and in the past has said it’s a hoax. He says he will declare American energy dominance a strategic economic and foreign policy goal.
He plans to "make America energy independent, create millions of new jobs, and protect clean air and clean water". He says he will conserve natural habitats, reserves and resources and “will unleash an energy revolution that will bring vast new wealth” to the US.
Mrs Clinton says she will work to fix the broken immigration system, will treat those who come to the US with dignity and respect and embrace immigrants, not denigrate them.
She says she will introduce comprehensive immigration reform within her first 100 days in office with a pathway to full and equal citizenship, while enforcing immigration laws humanely.
Mr Trump has said he will establish new immigration controls to boost wages and ensure open jobs are offered to American workers first; will curb "uncontrolled" foreign worker admissions; select immigrants based on their likelihood of success in the US and their ability to be financially self-sufficient; vet applicants to ensure they support America’s values, institutions and people, and temporarily suspend immigration from regions that export terrorism and where safe vetting cannot presently be ensured.
He also has a 10-point plan on immigration to "Put America First", which includes beginning work on an impenetrable physical wall on the southern border with Mexico, on day one, which, Mexico will pay for.
Mrs Clinton says she would expand background checks to more gun sales - including closing gun show and internet sales loopholes - and strengthen the background check system.
She says she will take on the gun lobby by removing the industry’s sweeping legal protection for
"illegal and irresponsible actions"
and will revoke licences from dealers who break the law.
She says she will also keep guns out of the hands of domestic abusers, other violent criminals, and the severely mentally ill and she says she will also support work to keep military-style weapons off the streets.
Mr Trump has said he will defend the Second Amendment of the US Constitution.
"The right of the people to keep and bear Arms shall not be infringed upon. Period."
He says he will nominate United States Supreme Court justices that will abide by the rule of law and the Constitution of the US, which includes upholding the Second Amendment.
He says he will enforce the laws on the books and prosecute violent criminals, get gang members and drug dealers off the street but he will also empower law-abiding gun owners to defend themselves.
He plans to fix the mental health system by expanding treatment programmes, and reform the laws to make it easier to take preventative action to save lives.
Mr Trump has said peace through strength will be at the centre of his foreign policy. He says he will achieve a stable, peaceful world with less conflict and more common ground.
He plans to advance America’s core national interests, promote regional stability, and produce an easing of tensions in the world. He will also rebuild the military and enhance and improve intelligence and cyber capabilities while ending nation-building and regime change.
He says he will work with Arab allies and friends in the Middle East in the fight against so-called Islamic State terrorists and will pursue aggressive joint and coalition military operations to crush and destroy IS.
He plans to defeat the ideology of radical Islamic terrorism and set up a Commission on Radical Islam to identify and explain to the American public the core convictions and beliefs of "Radical Islam", to identify the warning signs of radicalisation, and to expose the networks in society that support radicalisation.
Mrs Clinton says her top priority will be to keep the US safe and defend its values, which will include maintaining a cutting-edge military, strengthening alliances, cultivating new partnerships, defeating IS, enforcing the Iran nuclear deal, and being "firm but wise with rivals".
Mrs Clinton says that America is strongest overseas when it is strongest at home. To that end she intends to invest in infrastructure, education, and innovation to reduce income inequality so the US can lead effectively.
She plans to strengthen partnerships with NATO and Israel as well as invest in partnerships in Latin America, Africa, and Asia.
She says she will embrace diplomacy and development, to be on the frontlines solving problems before they threaten the US, this includes preventing Iran from acquiring a nuclear weapon; standing up to Vladimir Putin; and holding China accountable in cyberspace, on currency, on human rights, trade, territorial disputes, and climate change.
She also claims to have a "real plan for confronting terrorists" by taking out ISIS’s stronghold in Iraq and Syria, working with American allies to dismantle global terror networks, and hardening defences at home.
Mr Trump says he will rebuild the depleted US military including increasing the size of the US Army to 540,000 active duty soldiers. He will invest in a serious missile defence system to meet growing threats and to counter the ballistic missile threat from Iran and North Korea.
He will emphasise cyber warfare and require a comprehensive review to identify cyber vulnerabilities and protect all vital infrastructure and create a state-of-the-art cyber defence and offence.
Mrs Clinton says she is committed to restoring basic fairness in the US tax code and ensuring that the wealthiest Americans and large corporations pay their fair share, while providing tax relief to working families.
Mr Trump says he plans to reduce taxes across-the-board, especially for working and middle-income Americans who will receive a massive tax reduction.
He says he will ensure the rich will pay their fair share, "but no one will pay so much that it destroys jobs or undermines our ability to compete".
He will eliminate special interest loopholes, make business tax rate more competitive to keep jobs in America, create new opportunities and revitalise the economy. He also says he will reduce the cost of childcare by allowing families to fully deduct the average cost of childcare from their taxes, including stay-at-home parents.
Mr Trump has a seven-point plan to rebuild the US economy by fighting for free trade. It includes withdrawing from the Trans-Pacific Partnership; appointing "tough and smart trade negotiators" to fight on behalf of American workers; eliminating Mexico’s one-side backdoor tariff through VAT and ending sweatshops in Mexico that undercut US workers; instructing the Treasury Secretary to label China a currency manipulator and instructing the US Trade Representative to bring trade cases against China.
Mrs Clinton, despite having advocated for the Trans-Pacific Partnership while secretary of state, now does not support it. She says she supports trade agreements that would raise wages, increase prosperity, create more new, good jobs for Americans, and protect security. She says she would continue to cultivate trust and co-operate with China on a range of international challenges, like North Korea and climate change, while keeping competition within acceptable limits.
