Hey Aly - there are two incredibly useful resources -- at the state and federal level: State data at http://www.followthemoney.org/ and federal data at http://www.opensecrets.org/. The first, Follow the Money, is run by smart folks at the National Institute on Money in State Politics based in Helena MT. (See on JA at http://www.journalismaccelerator.com/resources/the-national-institute-on-money-in-state-politics-follow-the-money/). Open Secrets (we'll post on JA as a resource this coming week) is run by the Center for Responsive Politics based in WA DC. Follow the Money & Open Secrets collaborate with news channels large and small. Their staff - like Follow the Money - has a brilliant team of researchers, information advocates and deep experience in public policy. Many of their staff (across both outfits) have experience as journalists in service of open access to accurate, useful information created on the public’s behalf that gives people a tool to engage as citizens.
