If that happens, they're likely going to die.
Both are 75+ years old, and not in perfect health already. That's practically a death sentence if either (or both) of them end up with COVID.
Actually, as far as we've been made aware by medical records, Biden is pretty healthy aside from the age risk factor. IIRC the only major thing he's ever really suffered from are 2 brain aneurysms, but he was successfully treated for those over 30 years ago now. In any event, he's presumably in a much better position to recover from COVID if he were to get it compared to Trump, given the latter's other risk factors: obesity & (likely case of) heart disease.
