“Is it because we conservatives are universally mistaken, there is no fraud and the reality is only our own paranoia and grief over loss or....”
If the demonkkkraps and their major media outlets could prove that the conservative were mistaken, they would waste not a milli-second to bring forth the evidence, to be used to reinforce their legitimacy to the WH, but more importantly, to paint Trump and GOP as right-wing fanatical, power-hungry, anti-American, paranoid conspiracy theories. The absence of their taking the opportunity to tear down the opposition with long lasting, deep political damage speaks for itself - they would be exposing their own criminality with lasting, deep, irreparable political consequences.
Which leads to answer part of your “scary question”. The GOP lacks the discipline, the skills, the tenacity, the cohesiveness to get to the bottom of it. Despite Trump’s record of correctly calling out illegal spying, Russia hoax, Ukrainian hoax, etc long before the evidence emerged to prove him right ... they are influenced by the media and riots, cannot risk putting their perceived political futures on the line for Trump, when it really isn’t about Trump, it’s about free/fair elections.
Yes, that's it.
Joe Biden got 80 million votes, and Jeffrey Epstein killed himself.
And the thieves who shot Seth Rich in the back didn't take his watch or his wallet because they felt bad for him.
I am firmly convinced that the leadership of neither party, nor of multi-national corporations, nor of the billionaire caste want to allow any type of free/fair elections going forward. They want known quantities and guaranteed results. Like Gordon Gekko in Wall Street: "I bet on sure things." Stupid voters can't be trusted with picking their own leaders, after all - their betters must arrange it for them.
Wild cards like Trump and the MAGA movement scare the living daylights out of them. I would go so far as to say Ronald Reagan was the last freely/fairly elected President - Trump snuck under the wire in a fraudulent election that the fraudsters didn't quite calibrate correctly.
