The U.S. presidential election 2020 will be decided by 13 states that could swing to whether President Donald Trump, a Republican, or his Democratic rival Joe Biden. These states are playing a crucial role in delivering the 270 Electoral College votes highly needed to win the White House. Of the 13 states on this list, seven are still undecided, four have gone in favour of Trump and two have gone in favour of Biden. None of the decided states represent a change since the 2016 election. Due to a spike in mail voting amid the coronavirus pandemic – as well as the states' varying rules for when ballots can be counted – the final results for all the states are likely to take days.
