There are now almost 100,000 members of the Democratic Socialists of America. Because of this, the author of a critical biography of its founder is timely. The criticisms of Harrington are overwhelmingly true of the DSA today. Its anti-communism drives it to still support the Democratic Party in spite of the fact the party today is far more right-wing than it was in Harrington’s day. In Harrington’s day supporting Palestine was considered antisemitic. DSA’s support of Palestine today is more the affect of the brutal Israeli policy for decades than an internal change of heart on the part of DSA.
