I think very few of the so-called lies about contacts were lies. These people were meeting hundreds, if not thousands, of new people during a frenetic campaign that spanned a year. It is not surprising if they either couldn't remember a causal contact, or believed that such casual contact was not worth reporting.
Another thing is that the level of contact with Russia strikes me as quite low. I would bet that if you conducted the same audit of the Clinton campaign you would find a much higher level of contact with pretty much every foreign country on Earth, including Russia. It was the dossier (which is obviously total garbage) that focused intense scrutiny on the Trump campaign. It is a trivial matter to cherrypick from such intense scrutiny (i.e. ignore exculpatory information and only publicize inculpatory information) to cast any campaign or any person in a bad light.
Honestly (and I really mean this), I am surprised at just how "clean" Trump's campaign really was. I think they were probably just too overwhelmed and understaffed even to pursue nefarious deeds. The campaign was also too naive (or incompetent) to play the game the right way, like the Clintons do, with layers of intermediaries. For that reason, I think any illegalities would be easy to uncover. The fact that they haven't been uncovered yet is very strong evidence that they don't exist.
Well, as my bet with you shows, I believe that it does matter that the dossier was baseless, from a due process perspective. But, in any event, there is still no evidence for a dossier connected crime.
Manafort et al.'s crimes are from before the campaign and were already publicly suspected by the time the dossier alluded to them. That is, there are no allegations in the dossier with respect to Manafort's receipt of payments from the pro-Russian Ukraine party that the FBI (and the New York Times) didn't already know.
As for Papa-whatever, he is guilty only of a process crime. That is, he committed a crime only because he allowed himself to be interviewed by the FBI and then proceeded to lie to them (maybe). It will be interesting to see what Papa-whatever's punishment is. I bet it is extremely light. Probably a suspended sentence.
