The DNA thingy might have legs though no real validity. It is an attempt to “re-echo” the Clinton/Lewinsky and wrap Trump up in it. The chain of evidence is suspect in the same way that the “porno spygate” files were (and were later proven false). There must be a million ways to have gotten an ilicit sample of Trump’s dna over the years to be smeared on some lady’s old dress. Trump would have to had a diary of the exact date(the same way Kavanaugh kept one) of where he was at on the date she may claim to have been “raped by him” in order to have some defense. I’ve not read that she(the accuser) has stated when the rape was said to have occurred other than “30” years ago. We only have her word that the garment was in the exact same place since “that time”.
Those dressing rooms are wide open acoustically and what, no loud protestations or cries for help? Was it possibly consensual, a quick and naughty hook-up and then forgotten by Trump but always remembered by the woman?(I don’t believe that for a second but a possible he said she said defense with a quiet out of court settlement possible).
No court, civil or criminal would admit that dress or that DNA evidence.
