Very in depth project talking about why Super PAC's are bad for democracy, who's supporting them, how they work, etc... (also shows why it's necessary to stop them). Very interesting and clears up a lot of misconceptions and reasons as to why Super PAC's should be considered dangerous. Just as basic information a super PAC is a nonprofit that has been set up as a donation recipient that can receive money from just about anyone... the funds of which are then used in a political campaign. Why they're considered legal though is how the money is not allowed to be directed by the candidate or his staff, but there are plenty of ways to sleaze around this ruling. It would be a huge victory in cancelling the corruption of our government if we could stop these unregulated, anonymous payouts to government official candidacies. possibly through a good protest or law proposal:
