On September 13, 1948, Republican Representative Margaret Chase Smith of Maine won election to the United States Senate, breaking a significant barrier in American political history. After serving four terms in the House of Representatives—where she succeeded her late husband, Clyde Smith—she became the first woman elected to serve in both chambers of Congress. Her Senate victory also made her the first woman to represent Maine in either house of Congress.
Smith went on to build a reputation as an independent and principled public servant during a 33-year congressional career, including 24 years in the Senate. She achieved lasting national prominence on June 1, 1950, when she delivered her landmark “Declaration of Conscience” on the Senate floor. At a time when many politicians hesitated to challenge Senator Joseph McCarthy, Smith became one of the earliest senators to condemn the fear, personal attacks, and unsubstantiated accusations associated with McCarthyism.
In the speech, Smith defended core democratic freedoms: “the right to criticize,” “the right to hold unpopular beliefs,” “the right to protest,” and “the right of independent thought.” She warned against allowing political ambition to override constitutional liberty and national unity.
Smith’s 1948 election marked more than a personal achievement. Her work on defense, military, naval, and later space-related issues demonstrated that women could exercise durable authority in some of Congress’s most influential policy arenas. By placing conscience above partisan pressure, Margaret Chase Smith set an enduring example of political courage and independent public service.
