Harris and Trump tied in latest US election polls, as Tuesday’s debate nears

National and swing-state polling indicates a narrow race, with support for Trump remaining solid despite his change of Democratic rival

Donald Trump and Kamala Harris are in effect tied heading into the final weeks of the election campaign, according to a national poll conducted by the New York Times and Siena College, raising the stakes of Tuesday's presidential debate.

Trump is up one percentage point, 48%-47%, over Harris, according to the survey released on Sunday, a difference that is within the survey's three-percentage point margin of error, meaning a win for either candidate in the election on 5 November is well within reach.
