If you know nothing about Michael Harrington, this is the first book you should read. Or, if you think you know everything about him, this is your next book, guaranteed.
Doug Greene does a masterful job of giving Michael Harrington the political biography he has long deserved, and nothing is left out. From Harrington's humble beginnings as a Jesuit student, to his bohemian sojourns in Chicago and New York, to his entry into socialist politics and organizing with Max Shachtman, and his years-long development of the 'realignment' strategy, Greene takes the reader through Harrington's triumphs and setbacks, carefully explaining his political development in accessible and elegant prose.
Rather than isolating the context to Harrington alone, the history and development of American radicalism is the battleground Greene immerses his readers in, to great effect.
Harrington's relevance today is heavily accented in the introduction and conclusion, and though the book was completed after the 2020 primary but before the general election, the Democratic Socialists of America is still today being rocked by the repercussions of its choices in that election.
Greene tops off the book with an appendix summarizing Harrington's views under the heading The Meaning of Democratic Marxism, which Greene has helpfully condensed from Harrington's works, speeches, etc. This section alone is a valuable guide to the reader in studying Michael Harrington, and is worth the price of admission alone.
