They shared polling results, or at least, Manafort shared polling results with the Russian? Is that some sort of smoking gun? I know some in the liberal media are trying to make hay out of this.
Take it a step further and consider what a problem it becomes, if Manafort gave them internal data to get back into good graces with Deripaska. Subsequently, that information gets passed along to the Russian troll farm to drive issues and opinion. It won’t look good if Manafort provided information to a man under US sanctions, who then in turn gave that data to a hostile foreign intelligence service that interfered in the election process.
Remember how Judge Ellis wanted to see the classified and redacted information to know why Manafort’s finances related to the special counsel mandate? It’s likely we will find out this information was included in that portion and why Ellis ultimately concluded the charges were relevant.
