The Affordable Care Act (ACA), better known as “Obamacare,” was the most sweeping and consequential piece of legislation to become law in modern American history. It has touched nearly every American in one way or another, for better or worse, and it continues to cost people elections - or win them - ten years later.

In The Ten Year War, veteran journalist Jonathan Cohn offers the compelling story of the defining political battle of our time, one that will shape political conversations for decades. At the heart of the book is the decades-old argument over what’s wrong with American health care and how to fix it - but it also illuminates what went right, and looks forward to the next big debate over reform. But Cohn goes beyond policy to take a broader look at the profound and dangerous shifts in American politics. An authoritative, comprehensive history, The Ten Year War is a deeper look at how our government became so dysfunctional - and how our national political conversation became so polarised.

Drawn from hundreds of hours of interviews and private diaries and memos from the Hill, The Ten Year War is the defining account of a legislative effort and its tumultous aftermath that the United States will be reeling from for decades to come.
