The United States economy has gone from President Donald Trump's greatest political asset to his biggest weakness, a new study claims.
The economic fallout from the Covid-19 pandemic will cause Trump to suffer a "historic defeat" in November, a national election model released by Oxford Economics has predicted.
The study predicted Trump would win just 35 per cent of the popular vote, compared to a previous pre-coronavirus prediction that picked the president to win 55 per cent of the vote.
In 2016, Trump lost the popular vote, gaining 46.2 per cent to Hillary Clinton's 48.1 per cent, but secured victory by taking swing states such as Michigan, Wisconsin and Pennsylvania and Florida.
