Political scientists are rarely able to study presidents from inside the White House while presidents are governing, campaigning, and delivering thousands of speeches. It's even rarer to find one who manages to get officials such as political adviser Karl Rove or presidential counselor Dan Bartlett to discuss their strategies while those strategies are under construction. But that is exactly what Martha Joynt Kumar pulls off in her fascinating new book, which draws on her first-hand reporting, interviewing, and original scholarship to produce analyses of the media and communications operations of the past four administrations, including chapters on George W. Bush and Bill Clinton.

Kumar describes how today's White House communications and media operations can be at once in flux and remarkably stable over time. She describes how the presidential Press Office that was once manned by a single presidential advisor evolved into a multilayered communications machine that employs hundreds of people, what modern presidents seek to accomplish through their operations, and how presidents measure what they get for their considerable efforts.

Laced throughout with in-depth statistics, historical insights, and you-are-there interviews with key White House staffers and journalists, this indispensable and comprehensive dissection of presidential communications operations will be key reading for scholars of the White House researching the presidency, political communications, journalism, and any other discipline where how and when one speaks is at least as important as what one says.

Martha Joynt Kumar is a professor of political science at Towson University and the author and coauthor of several books on the media and the presidency, including the 1981 classic Portraying the President: The White House and the News Media, also published by Johns Hopkins.
