“This table lists the top donors to this candidate in the 2012 election cycle. The organizations themselves did not donate, rather the money came from the organizations' PACs, their individual members or employees or owners, and those individuals' immediate families. Organization totals include subsidiaries and affiliates.
Because of contribution limits, organizations that bundle together many individual contributions are often among the top donors to presidential candidates. “
It seems like a qualitative characterization of "where the money is coming from". Who knows how they aggregate the data or where it comes from; I I haven't looked into it yet.
