How Did One Man Cause All This?

President Trump had a premeditated plan to declare that the election was fraudulent and stolen before he knew the election results. He made his stolen election claims on election night against the advice of his campaign without any evidence in hand. Many of those who stepped forward to help, including Rudy Giuliani, knew they never had real evidence sufficient to change the election Results. In mid-December 2020, President Trump's senior advisors told him the time had come to concede the election. Why would Americans assume that our Constitution and our institutions in our Republic are invulnerable to another attack?Why would we assume that those institutions will not falter next time?
