What do you have to lose? If Trump cannot prove some of his allegations. He would have no basis for any further claims. News media can rub egg in his face without question or claim of bias.
If Trump can prove any and all claims, Biden would not be comfortable with any counting.
If I were a citizen of Georgia, I would not be satisfied until I had a count to disprove any charge. Trump would pay the total cost if claims were disproved. Of course the state would be liable for all costs otherwise. I really believe there are sufficient affidavits attested to by legal residents to justify further investigation by independent eyes.
Sufficient proof to justify overturning the current counts would have to be blatant disregard of voting laws.
As for basis for my claims, I have worked in WV elections and observed "irregularities" and some were reported to county, state and federal authorities. Of course nothing developed, and all three agencies used the same excuse as is offered in this case. "Don't question what you have reported, but taken together the charges would not be sufficiently enough to overturn the currently avowed to numbers."
