"[Rabin-Havt] offers an intimate portrait of his cranky boss, writing about everything from Sanders's famous mittens, to his love of picket lines and Motown songs, to his distaste for 'the inane droning of cable news commentators,' to his prescient fear that Donald Trump was 'nuts' and would upend democracy." —Maureen Dowd, New York Times

The Fighting Soul is an unforgettable chronicle of life on the road with Bernie Sanders and the first in-depth portrait of this fiercely independent, and famously private, left-wing firebrand. As a close advisor and deputy campaign manager on Sanders's most recent presidential campaign, the tireless Ari Rabin-Havt spent more hours between 2017 and 2020 with the Vermont senator than anyone else. The Fighting Soul is a behind-the-scenes account of Sanders's run, including his heart attack in Las Vegas, his notorious debate encounter with fellow progressive Elizabeth Warren, and a momentous private conversation between Sanders and Barack Obama. Revelatory and heartfelt, The Fighting Soul depicts the rare politician motivated by principle, not power.
