I follow legal analysts who were cautious from the beginning that the dossier was planted disinformation, and to the extent it was used for warrants is obviously an intelligence failure.
I hoped you watched the video I linked on how Russia is using it (on both sides) to spread dissent within our country.
As to Manafort, the Republican led, years long intelligence committee report decided Manafort had worked with Russian intelligence, and they in turn worked with Wikileaks to influence the election. Rudy said turning over the polling data was "bad judgement." Can you think of a possible legal explanation that Manafort would give US polling data to a Russian intelligence officer? Sharing it other Republican state parties makes sense. Sharing it with the Russians (so they could perhaps target US voters with Facebook ads to influence the election) seems to be a little out of bounds.

You'll recall Manafort was pardoned for his crimes, and to accept a pardon is an admission of guilt.
The FBI currently has a $250,000 reward for the Russian intelligence officer with whom Manafort shared polling data.

Since these were conclusions by Republican senators, I assume you might re-think your position. But, maybe not.
