Do you have real proof/evidence of this "vast election fraud"? So far none has been presented. And what "proof" is out there are either known falsehoods, crazy theories (zombie Hugo Chavez wants Biden and not Trump to win), or nonsensical (CIA/DOD/NSA radioactive isotope watermarks are applied to all legitimate ballots, any day now they'll show that x million ballots were fakes).
Other than the dishonest (to themselves or others), few are claiming no fraud. There's always fraud (either intentional or not), but usually (and so far this election seems no different) in the tens to hundreds of cases. But there's no evidence of millions of faked votes.
