This book was a long time in the making. It began many years ago as a conversation with Charles W. McCurdy. Early in 1980 he mentioned as a paper topic the effect of interstate commerce doctrines on the prohibition movement. Since then the work has grown. It has put down roots in various literatures, sprawled across far larger periods of time, blossomed with unexpected fruits, and required more tending and effort than this historical gardener would ever have imagined.

The greatest debts are those I owe to my family. Without their intellectual, moral, and financial support this work would never have begun, let alone been completed. At various times I lived with family members while researching or writing this work, and they all endured my stays with good cheer. Elaine Cascio sustained me more than I can ever say. She read various versions two or three times, proving that love has great patience. Her sharp editorial eye and common sense has made this a better book.
Also this work has benefited from a number of suggestions from various people coerced into reading it. At different times both Phil Merkel and Denise Thompson read the entire manuscript with pen in hand and removed hundreds of convoluted constructions. Richard Fiesta and Candice Bredbenner pointed me to literatures and interpretations that enriched the work. Christopher Lee, Jean Lee, and Robert Stanley made suggestions about issues that proved especially useful in rethinking the work at a particularly critical stage. Christine Paquette suggested a number of changes that improved both the introduction and conclusion.

Joseph Kett, Edward Ayers, and Calvin Woodard closely read the manuscript and suggested paths to follow in making it into a book. Stanley Katz, Robert Wesser, and Lewis Bateman expressed strong faith in the project, keeping me on track during the vagaries of the publishing process.
