Transparency Data (for AP)

Transparency Data. Looks like a pretty useful site for American Politics students who have a focus on lobbying and electoral campaign contributions. The following is its descriptions:

Transparency Data is a central source for all federal and state campaign contributions made in the last twenty years. Here you can begin your search, find the information you need and then download records of what a candidate has received, what an individual has given, and how much companies and their employees have given.
