Between now and the Democrat National Convention on August 19-22... just 4 weeks away, Biden won't be diagnosed by a doctor. Bet on it.

However, by September or early October, Biden will probably be diagnosed, and then decide to drop out of the race. Too late to get another Democrat candidate's name on the ballot. All mail-in ballots would have already been mailed out.

Democrats will end up having to organize a new candidate and a national write-in-vote campaign with only 30 days left. They can't electronically rig results for write-in candidates, which will have to be tallied by hand in every state. :>)
