  skos:definition "The Progressive Policy Institute (PPI) is a Washington, D.C.-based think tank dedicated to policy innovation and the modernization of progressive politics. Founded in 1989, PPI subsequently was dubbed “Bill Clinton's idea mill,” and many of its signature proposals (e.g., national service, public charter schools, community policing, and a work-centered approach to welfare) have been enacted into law.
