I don’t think it would prompt some kind of vindictive vote. That side of it is only going to energize those who were vehemently republican anyway. Republicans would hammer on any and all sympathy they can eke from having their candidate assassinated (regardless of the truth they will say it was the left, and at best people will think the guy was just crazy), and the average person only half paying attention will eat it up. Dems would be even more hamstrung in their rhetoric against the GOP considering the gravity of an event like that. Even with that aside, they’re now running Joe Biden against whichever face the GOP tells their voters to line up behind – who you can bet will be all in on the kind of stuff that will do even more lasting damage to our country. Biden is not a strong candidate, and without the uniquely unlikable personality and character of Trump I’m not sure there’s enough motivation amongst voters to carry him to another term.
But all of that was a lot to type, so I just said it would give them a massive boost
This is pretty standard, and maybe I can shed some light on it. You don the mask as you enter the room and take it off as you leave to avoid spreading the contaminate out of the room. The mask adds a barrier and reduces your risk of contracting whichever disease (and subsequently spreading it to other patients), and all the stuff it’s blocked stays in or at the room when you shed it. So the people seen doing that are actually playing their part in keeping whatever that person has limited to the room they’re staying in.
As for what people in those rooms have, it can be a lot of things, but it really is what it says on the tin. They have something that can spread by droplet, which ranges from the flu to stuff like whooping cough or, yes, COVID. The system to keep these things contained is pretty consistently updated and has worked well when implemented. We were all wearing masks everywhere for a time because COVID was spreading like wildfire, and concerns of people becoming contagious before showing symptoms with no way to reliably innoculate/vaccinate medical workers
