Ryskind was something of a socialist in his youth, but frustrated by the left's apparent sympathy for communism and disturbed by Roosevelt seeking an unprecedented 3rd term, Morrie abandoned the Democratic party for the Republican party, even going so far as the write the Wendell Willkie campaign song.

Later, he found the tactics and the slavish devotion to Stalin by Hollywood communists so appalling he appeared before the House Committee on Un-American Activities to detail their activities. For this he was blacklisted, and never sold another script.

He went on to become an articulate promoter of conservatism with a feature column in the LA Times. He was even a member of the John Birch Society for a short time but disassociated himself from the group when they started to claim that Roosevelt, Truman, and Eisenhower were part of the Soviet conspiracy. His son, Allan H. Ryskind, was the longtime editor of the conservative Washington weekly, Human Events.
