The Hesitant Senate
When JOSEPH S. CLARK was elected mayor of Philadelphia in 1952, he became the first Democrat in sixty-seven years to hold that office. Previously he had served as city controller of Philadelphia, and he teas active in the Committee of Seventy, which cleaned up corruption in that city. In 1956 he was elected to his first term in the Senate, where he is one of the most forthright and vigorous liberals.
