I know I can't speak for others, but this 100% entered our minds at the KP household. The wife wanted to go to a rally or two, but we decided it wasn't the time with COVID, especially since we didn't know how seriously people at the rally would be taking it. We couldn't tell our kid he couldn't go to the gym and then have her go do that. That said, a lot of the pics from th event seemed to have a bit higher mask wearing % than my normal trip to the store on the weekend.
However, I do think that it's pretty telling that we would say it's hypocritical to hold the POTUS to a different standard than Joe Citizen on the street. I would expect the president and any person running for high office to have different safety measures and guidelines when it comes to COVID.
