Its probably all intentional.
Intentionally present cases with huge technicality issues(misspellings, wrong procedures, etc...) so the judge doesn't even want to waste the court's time.
People like Tom then point to it and say "See? Proof she's right! They won't even look at the evidence, its so powerful and would ruin democracy!".
So Powell and her ilk get to keep pedling the claims without having to also prove it in a court of law. And Trumpers just eat it up.
