Oddly, we could all tell the difference in the air 'smell'? Can't explain, but there was a difference.

Probably ozone. Low levels of ozone is what gives that "fresh air" smell accompanying a thunderstorm, combined with the rain having swept a lot of dust out of the air.

Another device we used in the old days in Lubbock was an electrostatic air cleaner. They still use them in bars and other dwindling places where people are allowed to smoke, to yank the smoke particles out of the air.

It works by emitting electrons. These attach to air molecules, creating negatively charged ions. The atoms want to get rid of the extra electrons, but the only thing around are the surfaces of assorted particles suspended in the air. As these particles accumulate excess electric charge, they can be moved by electric fields.

In most of these devices they use about 30,000 volts or so to produce the electric charge difference. There is this "fuzz" that is metal made where it has millions of tiny spikes, where the surplus electrons build up and are squeezed out into the surrounding air. A few inches away are some metal plates that either are at ground or at a fairly high positive potential.

The surplus electrons are attracted to the relatively positive collection plates, and since they have become attached to the smoke particles, they are drawn to the plates just like fine bits of paper are drawn to a comb after you rub it on the cats' fur.

The net current is relatively low, a few microamps at the most, but it quickly pulls an incredible amount of smoke out of the air that is drawn in at one end.

The movement of the smoke particles and charged air also produces a gentle breeze, and once the surplus electrons are stripped off by the plates, the now neutral air molecules are able to keep going, emerging nice and clean from the discharge end, while leaving the smoke particles collecting as a yellowish gunk on the plates.

After the bar closes, they would shut down a unit, discharge the high voltage (much like the TV picture tube flyback circuit in the old days), and then remove the collector plates. Some versions of these, you could just run the plate assembly through the dishwasher to clean off the condensed smoke. There's probably more stringent hazmat disposal protocols in place today other than just flush nicotine laden sludge dissolved in soapy water down the drain to the sewer plant.

They'd let most of them run a bit longer to get the residual smoke out of the air, before shutting down for cleaning. Depending on how much smoke was left, they might leave some of them running longer, or restart some cleaned ones to run all night and day to further clean out the air.

They made the crud build-up on everything else a lot less.

I've heard of people using the technique to "bake out" the stench of a car that has had a smoker driving it. They put one of these devices in, possibly also with activated charcoal, and then keep the interior of the car heated up to about 175 degrees F or so (or parked in the desert sun) and run the smoke collector for a few days.

I love the heat, dislike the cold!

I loved the snow until I broke something. I love heat now. Have portable AC but prefer to open a window for the heat.

Wouldn’t people who get exposed from a convention be back at home by the time it incubates?

Sure, but think about it.  Every elected Arizona Republican would be present! Most of the Republican power brokers from all 50 states. Half the R elected officials and A ton of media From all over the US and the world.  So, the virus might as well be let loose in La Guardia, LAX and O'Hare simultaneously.  Maybe add SeaTac and a couple other airports.

That would be my working hypothesis.

Same if a protest crowd of 50,000 were all exposed, although the transmission rate outdoors is a lot lower than indoors.

Now those that end up arrested, even if just given citations after a couple of hours in the back of a paddy wagon, or bunched up in a tent somewhere, would have a much, much higher number exposed and then contagious for a while before developing symptoms themselves.

I guess we will see what happens. Although no one seems to care about the violent protestors spreading it, which is much more likely since they aren't distancing or even pretending to.

Yes and by then it would be difficult to tell.

Yeah. so maybe no one else should travel for a few days before and after the end of the convention, so the next super-spreader outbreak won't get passed along to everyone else who was just in the airport that day some dignitary, security personnel, aides, etc. are all exhaling clouds of virus acquired at or around the convention.

That also made me think of something else that actually has historical precedent although I can't remember much detail beyond it was evidently in the 19th century.

While it's pretty cut and dried how succession operates if a President in office dies - such as when FDR kicked the bucket and Truman stepped up, or when JFK had his -um- misadventure in Dallas and LBJ stepped up. Same with resignation, or even a pair of resignations. Spiro Agnew resigned, Nixon appointed Gerald Ford as a replacement for Agnew to finish the term, then Nixon resigned and Ford stepped up.

But - what about if, say, a major party nominee kicks the bucket between convention and election? Let's say, maybe both the top and bottom of the ticket contract, say, a disease, and neither makes it to Election Day. Or, say, the VP nominee recovers, and the Presidential nominee doesn't. It's too late to re-print ballots.

Then there's the problem of - same scenario but between the election and the inauguration, for whoever won.

Because neither of the presumptive names on the ballot in November are spring chickens. It wouldn't even have to be a pandemic. I've known far too many folks in their 60s and 70s who at 7 PM one day thought they had a bad case of acid reflux, and by 7:15 PM people were frantically doing CPR waiting for the ambulance, and by 8 PM the E.R. doctor  officially pronounced them.

Then there's an even more murky scenario. Let's say that both major party candidates have been showing symptoms of serious cognitive decline, sometimes speaking or tweeting word salad, sometimes forgetting the kind of things that suggest not really knowing where they are or what they are talking about.

So by Election day, they're both, say, quite alive, but it's clear that the lights are on but nobody's home. How would that kind of situation be handled?

Um, that is already kind of the case with one possible nominee.   They would just plug in the VP candidate.
