Maybe because even Republicans say it didn't exist. Even Trump's own Attourney General of the United States refused to investigate further because he said it did not happen. 62 judges who had cases brought before them on supposed election fraud found that 0 of the cases had merit. In fact, those lawyers that brought the accusations of election fraud before the court are actually up for being disbarred because of blatant lies before the court. You see.. In court, you cannot blatantly lie to the judge without proof to backup your claims.. Because under your law license, that's against the rules.
