And not just PACs - there is 'deep spending', on propaganda media: Breitbart, IJR, NY Post, WSJ, and on foundations: Jud Watch (has spent $500M in last decade to attack Bill and Hillary), ALEC, SPN, Cit U (that Supreme Court decision was planned by billionaires).

There is a huge incentive for billionaires to spend money on propaganda, because they need votes for their pro-wealthy policies, which almost no voter would support without propaganda.
