Paul Blumenthal for HuffPo:
At the end of January, there were 59 donors who had given $500,000 or more to at least one super PAC. These donors, whose contributions total $80.12 million, accounted for 61 percent of all contributions to super PACs. Contributions from donors giving over $100,000 — $111.1 million in total — account for 85.5 percent of all super PAC donations.
“Super PACs are for the 1 percent,” said University of California-Irvine election law professor Rick Hasen.
Just who are the 59 donors who have given at least $500,000?
Forty-one are individuals. Nine are corporations. Seven are unions. The final two are a trade group and a nonprofit funding their own super PACs.
