Political scientist Samuel DeCanio examines how political elites used high levels of voter ignorance to create a new type of regulatory state with lasting implications for American politics. Focusing on the expansion of bureaucratic authority in late-nineteenth-century America, DeCanio's exhaustive archival research examines electoral politics, the Treasury Department's control over monetary policy, and the Interstate Commerce Commission's regulation of railroads to examine how conservative politicians created a new type of bureaucratic state to insulate policy decisions from popular control.
