Investigating Organizations

How can I check up on a nonprofit group? What information is available on corporations operating in my state? What can I learn about labor unions? What can I learn about an employer’s record on workplace safety?

Campaign finance, lobbying and elections

How can I dig into state campaign finance data? How can I find who is lobbying whom over what? How do I find similar information on campaign finance and lobbying in other states? How do I track campaign donations and spending for federal candidates, like U.S. senators and congresspeople? How can I correlate contributions to votes?
