Good find!
I think Manafort’s main/most serious offense is money laundering. The “not registering as a foreign agent” charges appear to be very minimal—I’ve seen it described as an error that is corrected by re-filing paperwork.
It seems the only way Podesta is going to be in serious trouble is if they can find that he laundered money as well.
