Yep. The scum who control most of the power levers at the upper levels of the GOP are going to try every dirty trick you can imagine and more to try and screw him over. And when they do, it’s going to be really ugly.
Keep in mind that "four dead in O-HI-O" really happened, when Natiional Guard shot at Kent State protestors. The police have been slow to stop BLM protestors, besides which they don't want a repeat of the historic Kent State event. I would suspect that if things start to get out of hand they won't keep the anger reined in.
I really hope the Republican elite have at least an ounce of love for America and don't attempt to steal the election. I don't mean for this to be a threat. It's a reality check from someone who remembers the 1960s.
