That's a bit of a simplification. I've had, and continue to have discussions with my (American) daughter-in-law's family, who I consider sane, sensible and quite intelligent. The younger ones are anti-Trump but also were worried about Biden. One of the older ones said to me "I don't like Trump but I prefer him to Biden". It wasn't a great choice, a bit like having to choose between Johnson or Corbyn. At least we had other choices.
Incidentally, one of the guys injured in the shooting is a close friend of my daughter-in-law's uncle, and my son played in a band with him. He's actually a Democrat and is in hospital with a Secret Service guard on his room, which seems a bit OTT but is probably more to protect him from the media than anything else.
