When Winthrop Rockefeller was elected governor of Arkansas in 1966, he became the first Republican to hold the governor's office since Reconstruction. Cathy Kunzinger Urwin examines Rockefeller's tenure by looking beyond his immediate successes and failures to the broader, dramatic changes that marked the era. Rockefeller helped break up the political machines that had controlled Arkansas politics for almost a hundred years, made lasting contributions in the areas of prison reform and civil rights, and obliged the Democratic Party to find Dale Bumpers, a young, bright, progressive gubernatorial candidate to oppose him in 1970.
