The Hill has tabulated scores that Washington advocacy organizations give members of Congress, so you can check them at thehill.com rather than roaming the Internet from site to site. We cite 31 organizations, which is a fair cross section rather than a comprehensive list. Click on a lawmaker's name to see his or her page.
