"Observers have long marveled at the spread of ideas and policies from state to state in American democracy. But why and how do politicians, professionals, and citizens in one state take inspiration from national policy debates and imitate, resist, and rework legislative models from other states? For the first time in this important new book, Andrew Karch analyzes in depth the process of policy 'diffusion' across the states, offering a nuanced and powerful framework to explain one of the most important and recurrent features of U.S. politics."
