From my point of view the reason for an increasingly violent election, with 2 guys trying to shoot Donald duck Trump, is pretty simple: violence brings more violence, and that a cycle of life that appeared many time in history. Many times the trigger was and still is family, for other people that trigger is honor, or money or whatever because the reason depends of each person being triggered. He reacts, ther people being hurt in some way by his or her actions are reacting, and the violence erupts because each reaction is bringing more and more violence.
Donald duck Trump has been verbally violent in the last years and that triggered some guys to guns and they tried to shoot him. That should have been expected in a countru that allows people to have guns, and the authoriries from FBI and Secret Service should have been prepared for that. I have no idea what's going to happen in the future, I can't predict it so good, but it's very possible that some other stupid people to shoot Donald duck Trump and one of them could kill him. Time will tell and we'll see if that is only an idea or something real, so be tuned.
