The Center for Public Integrity (CPI), a Washington, D.C.-based accountability group, recently ranked all fifty states on their lobbyist reporting laws.      CPI based its rankings on a detailed analysis of the definition of a lobbyist, lobbyist registration requirements, reporting requirements for individual lobbyists and their employers, whether the state allows electronic filing of reports, public access to records, enforcement of the reporting law, and whether the law requires a "cooling off" period before a legislator can become a lobbyist.      The state of Washington scored highest, with 87 out of a possible 100 points. Most states scored failing grades (below 60). Wyoming came in at 49th with 34 points, followed by Pennsylvania with 0 (after a court decision struck down Pennsylvania's reporting law).      Wyoming scored particularly poorly on spending disclosure and enforcement. Both are addressed in the ESPC's proposal for a comprehensive lobbyist reporting law (see page 4).
