That is just a typical leftist copout. They dishonestly claim that if they hid their fraud well enough then they must be automatically believed when they say they did not commit voter fraud. No, they must not be believed without proof and they offer no reasoning why hundreds of thousands of unverifiable ballots that were taken in at key democrat precincts at night with no observers recording their activities as required by law were counted.
Yup, it's on those making the claim. Between Trump, Giuliani, Powell, Lindell, lawyers bringing nothing to the table in cout and audits confirming no such fraud took place there's squat to be accountable for, other than those still buying into it being gullible dupes.
The burden of proof is on the democrats to prove Trump colluded with Russians but they failed - miserably- after wasting tens of millions of dollars and tied up 3 years of valuable time that could have been spent on important things that mattered. Democrats don't care for proof, they only care for ways to cover their crimes, dishonesty, and corruption.
