Additionally, over 3,500,000 people have recovered from the coronavirus in the US.
Earlier week a US political commentator told Express.co.uk Donald Trump’s handling of the COVID-19 crisis in America over the coming months will be crucial in deciding the result of the 2020 US Presidential election.
Jadan Horyn stated the coronavirus pandemic will be a liability on President Trump’s election campaign but reopening the economy will be a factor in his favour.
He added that decreasing COVID-19 cases and a healthy economy will hurt the Democrats’ chances of defeating the US President.
“I don’t know if the media are going to cover that because they won’t want to give the President credit but that will be a factor.
“The economy reopening will also be a factor, that could play in the President’s favour.
“There are somethings that I do believe that are outside the scope of the narrative either party would want.
“Increasing cases would hurt the President and the Republicans and decreasing cases and a healthy economy in general would hurt the Democrats no matter what they are saying.”
