(Not sure if this should be on the Law.SE)
Per title. Most of the news coverage I've seen have said the challenges are bad, such as this recent one on the result of a challenge in Pennsylvania.
"One might expect that when seeking such a startling outcome, a plaintiff would come formidably armed with compelling legal arguments and factual proof of rampant corruption," he wrote. "Instead, this court has been presented with strained legal arguments without merit and speculative accusations ... unsupported by evidence.
Russell J. Ramsland Jr., a cybersecurity worker and an expert witness in the case, filed an affidavit Wednesday claiming that his company had uncovered evidence of inconsistencies in electronic voting machines. But the inconsistencies he claimed to identify were in districts in Michigan, not Georgia.
The affidavit also listed a number of towns and counties in which Ramsland’s analysis ostensibly showed that the number of votes cast exceeded the number of eligible voters. But most, if not all, of the places Ramsland listed appeared to be townships and counties in Minnesota, not Michigan.
Taken at face value this would imply that the legal cases are really bad, effectively wasting the courts' time. That in turn implies that the judges would've handed down a frivolous litigation judgement with associated penalties for the plaintiffs. But if that has happened, I've not seen it reported in the media. Why?
A first guess is that there is no law against frivolous litigation in the US, but Wikipedia seems to indicate that's not the case.
