Editing Maurice Spector (section)

== Leaving Canada ==
Spector moved to [[New York City]] in 1936 and became a leading member of the Trotskyist movement there. He presented the International Report at the founding convention of the [[Socialist Workers Party (United States)|Socialist Workers Party]] at the end of 1938 but dropped out of the party in 1939. (Contrary to some reports, he did not take part in the 1939-40 debate between [[James P. Cannon|James Cannon]] and [[Max Shachtman]].)

He joined the [[Socialist Party of America]] shortly after leaving the SWP in 1939 and remained on its executive body until 1958, when he resigned after breaking with [[Max Shachtman]] and his proposal to merge Shachtman's [[Independent Socialist League]] with the Socialist Party, which Spector anticipated would move the SP to the right.<ref name=palmer>{{cite journal|last1=Palmer|first1=Bryan D.|title=Maurice Spector, James P.

In his later, Spector became editor of a children's magazine published by the [[Labour Zionist]] movement.
