Via Mike Crowley, the AP breaks down presidential giving by employer. Barack Obama's biggest sources of funding, for example, are all investment firms: Lehman Brothers, $160,760; Citadel Investment Group, $152,150; Goldman Sachs, $103,550; JP Morgan Chase, $101,950; Citigroup $61,125. John Edwards, by contrast, has two investment firms (Fortress and Goldman Sachs) plus two law firms -- Lerach Coughlin and the Watts Law Firm. Bill Richardson's best fundraising haul comes from employees of the State of New Mexico.

Hillary Clinton's number two company, it turns out, is Cablevision, the company that destroyed the New York Knicks.
