At this point, the important thing to remember is that the dossier was a political operations research product that was used by the FBI and the intel community to create the premise that the Trump campaign was colluding with the Russians, which was then used as the basis for a FISA warrant that allowed them to bug Trump and his staff, campaign and transition.
It's unbelieveable. And the sheer chutzpah of the Dems and the media, who STILL trot out Watergate as the standard of wrongdoing, is breathtaking.
