2011 is a year for elections on many levels in the U.S. Want to know how money affects what politicians support and vote for? Check out MapLight.org, a nonprofit, nonpartisan research organization that reveals money’s influence on politics. (MapLight stands for money and politics.)
Elected officials collect large sums of money to run their campaigns, and they often pay back campaign contributors with special access and favorable laws. This common practice is contrary to the public interest, yet legal.
MapLight connects data on campaign contributions, politicians, votes, industries, companies, and more to show patterns of influence that could never be seen before.
