He Dems.....if Trump is guilty....who would know?

Answer: Manafort

As far as I can tell Manafort is in a mountain of shit for some shady dealings he had before Trump ever thought of running for president. That seems like the kind of thing you might bail yourself out of by calling in a mega favor, blackmailing the president, or simply making a deal for immunity with Prosecutors.

Whistleblowing on Trump would be the the Holy Grail for ANYONE with knowledge of Trump/Russia collusion. Think of the accolades. Think of the book deals you would get. Think about how much you could charge CNN to be a guest commentator.

Instead, the guy is looking at alot of federal prison time. Explain how that's possible if he has an ace in the hole?
