Dewey also agreed to debate Stassen in Oregon on national radio. Held on May 17, 1948, it was the first-ever radio debate between presidential candidates. The sole issue of the debate concerned whether to outlaw the Communist Party of the United States. Stassen, despite his liberal reputation, argued in favor of outlawing the party, stating his belief that a network of Soviet-directed Communist spies "within the U.S. demanded immediate, and punitive, response...Why did Dewey oppose such a ban? Stassen wanted to know." "We must not coddle Communism with legality", Stassen insisted. Dewey - while criticizing Communist totalitarianism and Soviet actions in the Cold War - still forcefully argued against banning the Communist Party: "This outlawing idea is nothing new...for thousands of years despots have tortured, imprisoned, killed, and exiled their opponents, and their governments have always fallen into the dust." Dewey ended his turn in the debate by stating that "I am unalterably, wholeheartedly, and unswervingly against any scheme to write laws outlawing people because of their religious, political, social, or economic ideas. I am against it because it is a violation of the Constitution of the United States and the Bill of Rights...I am against it because I know from a great many years of experience in law enforcement that the proposal wouldn't work. Stripped to its naked essentials...this is nothing but the method of Hitler and Stalin. It is thought control...an attempt to beat down ideas with a club. It is a surrender of everything we believe in." Surveys showed that from 40 to 80 million people nationwide listened to the debate, and most observers rated Dewey as the winner. Four days after the debate, Dewey defeated Stassen in the Oregon primary. From this point forward, the New York governor had the momentum he needed to win his party's second nomination.
