The outcome of the Gates or Manafort case really aren't too important to me as they really have nothing to do with Trump. And even that ruling can likely be taken up the court chain with appeals, so I'm not sold on anything yet. Personally, I am just in sit and wait mode with those two and with Trump most of the allegations are ridiculous. If Mueller gets pulled into the whole Comey and McCabe fiasco he's going to stop investigating and batten down the hatches. I foresee this as the most likely outcome. I have no doubt Manafort and Gates are already screwed in every conceivable way, but it's just a matter of 'how screwed' they are.
It still doesn't change my opinion that Mueller is over-reaching and doing some shady side deals. Mueller is all tied up in the Uranium One fiasco and that crap is going live soon - I've heard investigators have videotapes so this isn't mere assertion. There are bribes, side dealings, and other federal officials with hands so dirty it'll make the rest of this look pathetic by comparison.
