It should be remembered that nothing Manafort has been indicted on has anything to do with the campaign except that Manafort lied through his teeth while running it.
It mean something totally different than what the talking heads have decided. Mueller is going back to 2010 and dragged the first indictment from someone who was taking foreign money (puppet of Putin) for political gain and self enrichment. Who else would have been a prominent politician taking money from foreign governments for self enrichment in 2010? Clintons perhaps? More congressional people involved? If Mueller really is interested in justice, then this might be an indicator that he has thrown his net out for all of the ‘collaborators’.
