Hyperpartisanship has gridlocked the American government. Congress' approval ratings are at record lows, and both Democrats and Republicans are disgusted by the government's inability to get anything done. In It's Even Worse Than It Looks, Congressional scholars Thomas E. Mann and Norman J. Ornstein present a grim picture of how party polarization and tribal politics have led Congress—and the United States—to the brink of institutional failure.

In this revised edition, the authors bring their seminal book up to date in a political environment that is more divided than ever. The underlying dynamics of the situation—extremist Republicans holding government hostage to their own ideological, antigovernment beliefs—have only gotten worse, further bolstering their argument that Republicans are not merely ideologically different from Democrats, but engaged in a unique form of politics that undermines the system itself. Without a fundamental change in the character and course of the Republican Party, we may have a long way to go before we hit rock bottom.
