Twenty-first-century America isn't working the way it's supposed to. This book explains why.

Americans in the twenty-first century are becoming increasingly untethered from both reality and the essential principles and traditions that have shaped the nation's historic success. A big part of why America isn't working is because far too many Americans neither know nor care how it's supposed to work.

Cooper explains key aspects of recent US political history to give the background to dangerous developments, including how political groups have reshaped since the 1964 Civil Rights Act, the rise of Newt Gingrich and the Tea Party, the profound impact of the internet and social media, and the threats posed to the electoral system by the growth of extreme polarization and growing irrationality.

Cooper shows how these recent developments have their roots in the deeper past, with the establishment of the political system in the first place and all the knocks and tweaks to it along the way. He also reveals how, as a result of increasing politicization, the US Supreme Court is now exacerbating polarization instead of acting as an effective check on executive power.

How America Works...and Why It Doesn't is an accessible guide to the US political system which provides a rational and compelling explanation of the ongoing threat to American democracy.
