An earlier version of this graphic incorrectly included donations to Winning Our Future, a super PAC supporting Newt Gingrich, in the donation totals of individual super PAC donors. Those donations have been subtracted from each donor's contribution amount. Summary totals were not affected, as those totals were not counting any contributions to Winning Our Future.
