As Congress inches toward major immigration legislation, a new Sunlight Foundation analysis (based on almost 8,000 lobbying reports) offers a comprehensive and interactive guide to the web of interests with something at stake. As legislation continues to take shape, a wide range of sectors will continue flooding Congress with their lobbyists, trying to make sure that their particular concerns are fully addressed. The visualizations we present can help to better understand who these interests are, what they care about, and how intensely they are likely to lobby to get what they want.
