The advent of super PACs has been criticized by both Republicans and Democrats this cycle, showing a growing disillusionment with a small number of individuals pouring money into politics, attempting to influence voting outcomes. According to The Washington Post, 41% of the money raised by the groups this cycle comes from a minuscule group of 50 mega-donors and their families. The largest donor of the group is Democrat Tom Steyer, who has donated $17 million so far and has said he plans to spend more than $70 million by the end of the cycle.
