_Anything_ could happen between now and the convention/election. Surprisingly, I haven't seen this mentioned explicitly, but all of the remaining (major) candidates are squarely in the Covid-19 "danger zone". Some are known to have complicating health factors and there's a non-zero possibility that others do (despite what their doctors' notes say), which _doubles_ the risk.
