Trump, and his gang of grifters and pickpockets, could produce overwhelming evidence of voter fraud and it wouldn’t make a lick of difference in the criminal case against them. Nor does it matter if they believed their own bullshit. None of that is material to the conspiracy of crimes they’ve been indicted for.

They’re guilty and they have no defense other than obfuscation or misdirection, which may work in public relations but not in court.
