It really is quite alarming. My state's governor got 4.5 million dollars from... nobody knows. It's all hidden behind non-profits. You have super PACs giving to non-profits to help hide it even more. Suddenly everything is getting contracted to out of state contractors without letting in state ones bid. Not at all suspicious!
The people profiting from this system are also stupid and short-sighted. You might enjoy a dark money system when it's just donations from your favorite special interest groups... but one day, you get a polite call informing you that they've compiled a press package about how a third of your campaign money came from the Solntsevskaya crime group and if you don't want it released, they have some legislation they want you to vote on.
Dark money has no place in a democracy.
