I don't think it was staged. But I am also not sure this will help him a great deal. He was pretty unsympathetic before he was shot. I don't know how many people will change their minds about him, but who knows? It will be pretty dumb to fight for the NRA when the whole reason someone had access to the gun was because of his own policies. Karma?
If anything, it gives him more conspiracy webs to spin about the supposed Deep State. We can only hope the GOP takes it overboard and alienates independents.
