No you did not. Trump TOLD you that's what you saw, but he has absolutely NO EVIDENCE to back up such claims.
Every count, recount, audit, and even the Arizona Fraudit confirmed that there was no fraud, no ballot stuffing, and the only people who have been convicted of election fraud, have been Republicans voting for Trump on behalf of dead relatives. More than 80 judges looked at the cases filed and found there was no foundation to anything claimed by these law suits.
Anyone can take a video of the counts and tell you something nefarious is going on because you don't know what is supposed to be going on. In court, election officials came in, told the court what was really going on, and the cases were dismissed.
Trump is lying, and he continues to lie, and you continue to believe his lies, despite all evidence to the contrary.
