The impression I've always had was that money laundering, as long as they dont mind losing a big chuck of their cash by doing it, is pretty easy - and therefore if they saw the value in getting it into a legal banking system (to lobby through a non-illegal front) it wouldn't be impossible, just more expensive than lobbying with legal money. But the extent of my knowledge on money laundering comes 30% from an old friend who used to work for a bank detecting it and 70% from breaking bad, so could easily be wrong!
