I would love to know the answers to those questions. But bringing them up doesn't have any bearing on Trump organizing fake electors. Who set those bombs, even had they gone off, doesn't have matter one lick as to Trump's actions. Unless of course he directly ordered them himself, if that's what you're implying.
"Fake electors" is just nonsense narrative.
Trump is allowed to pursue every legal avenue to challenge the election, and the alternate electors were just that, a potentiality that never occurred because a successful challenge, or any challenge, was never allowed due to the rioting.
It's all jus BS dem/media narrative you're eager to regurgitate about fake electors being automatically assigned by Pence. That was never a possibility.
