The Rainmakers: California's top political donors, 2001-2011

Lavishing their largesse on legislators and political committees alike, the largest donors to California politics spent $1.25 billion from 2001 through 2011. The group — 50 special interests and 50 wealthy individuals — spans the Golden State's social order. They are corporate leaders and venture capitalists, real estate developers and Hollywood scions. They are energy and tobacco companies, labor unions and tribal governments. Collectively, they shelled out a third of all the money given to campaigns in the state during the 11-year period. This data includes only contributions to candidates and ballot measure committees, not independent expenditure groups.
