Casinos, public employee unions biggest campaign donors

by NW Spotlight

A compilation of campaign contribution data shows that nationally, the top 15 donors are led by casinos (including Indian gaming) and public employee unions (NEA, SEIU, AFSCME).

The National Institute on Money in State Politics and the Center for Responsive Politics collaborated to compile a unique view of the top 10,000 donors to political campaigns at both the state and national level. Their data is from state and federal campaigns, political parties, and ballot measure committees in 2007 and 2008.
