Despite the progress of decades-old disability rights policy, including the landmark Americans with Disabilities Act, threats continue to undermine the wellbeing of this population. The U.S. is, thus, a policy innovator and laggard in this regard. In Politics of Empowerment, David Pettinicchio offers a historically grounded analysis of the singular case of U.S. disability policy, countering long-held views of progress that privilege public demand as its primary driver. By the 1970s, a group of legislators and bureaucrats came to act as "political entrepreneurs." Motivated by personal and professional commitments, they were seen as experts leading a movement within the government. But as they increasingly faced obstacles to their legislative intentions, nascent disability advocacy and protest groups took the cause to the American people forming the basis of the contemporary disability rights movement. Drawing on extensive archival material, Pettinicchio redefines the relationship between grassroots advocacy and institutional politics, revealing a cycle of progress and backlash embedded in the American political system.
