If Trump wins the election one of two things will happen, either the left will be so busy burning down the country it will take top spot in the news, and COVID coverage will dissipate..
Or, COVID coverage will stay top spot in the news just to hate on Trump and keep people riled up.
However, with vaccines on the horizon, it won't be very long lived.
If Joe Biden is elected, by the time he takes office vaccines will be on the market and there won't be anything to talk about, other than how Joe Biden "saved the day" while ignoring that without Trump we wouldn't have any vaccines...
So it really depends on who wins how it will be covered.
