Trump will obviously order everything up to and including voodoo in order to stay alive until the election, and I say the more, the merrier. He will look and sound like death warmed over if his illness progresses and he doesn't isolate himself. If he holds a rally and looks like he is a refugee from a wax museum and sounds like a character from a horror film, it won't do him any good.
When asked his opinion, Biden will wisely say he didn't see the video, and really has more important things to do. That will deprive the Republicans of footage they would otherwise show on Fox to show how heartless Biden is, and they already have an uphill battle if they want to portray Biden as heartless, since a greater "mensch" has seldom run for President.
When Spiro Agnew got called on his offense while still in office, Nixon, probably against his own instincts, chose the well-liked and respected Gerry Ford to replace him. That made it easy for the Republicans to accept when he resigned, because a Republican replaced him that didn't turn the country against their party in general. Richard Milhous WHO? Never heard of him. If Ford hadn't pardoned Nixon before he was even indicted for anything, Jimmy Carter would have just been a footnote to history, and Ford wouldn't have had the dubious honor of being the only president never to have been declared the winner of a presidential election. Frankly, I'd prefer that Pence not get that honor, either, or if so, as a caretaker lame duck who serves out the last few months after the election. I do not want to see a bunch of frivolous Republican lawsuits get traction, and postpone the election.
Not only should the election go as scheduled, even if Trump is comatose by the time it happens, but I want to see a Democratic Congress enact laws that make it a serious felony to deny citizens the right to vote, or to enforce unconstitutional regulations that restrict that right. Armed goons at polling places that try to intimidate voters need be carted off by more heavily armed Feds, and then go away for a mandatory ten years at hard labor. So do those who throw away voter registrations, set up robocalls with false voting information, or tamper with or misprogram voting machines, and ALL voting machines need to be forensically tested after giving their tallies. Notice that everyone even accused of these crimes is ALWAYS helping Republicans. No more incidences like that one machine in Ohio in 2004 that gave Bush 3000 votes in a precinct with 600 registered voters.
