Minnetonka-based Cargill, Inc., America's largest privately held corporation, has pocketed more than $1 billion in federal business as a result of its political pull. The Sunlight Foundation, a Washington, D.C. money-in-politics watchdog group, found that Cargill invested almost $10 million in campaign contributions and lobbying between 2007 and 2012, making it one of the Top 200 sugar daddies on Capitol Hill.
