Fred Siegel of Cooper Union really liked this book that proposes that we analyze US political history in three eras. The current era is one in which political affairs are defined by voices outside the parties.
Here is what the Oxford University Press wrote about this book:
"Hailed in The New York Times Book Review as "the single best book written in recent years on the sweep of American political history," this groundbreaking work divides our nation's history into three "regimes," each of which lasts many, many decades, allowing us to appreciate as never before the slow steady evolution of American politics, government, and law."
Here is the book:
