The Kennedy Family had long been leaders of the Irish Catholic wing of the Democratic Party; JFK was middle-of-the-road or liberal on domestic issues and conservative on foreign policy, sending military forces into Cuba and Vietnam. The Kennedy style called for youth, dynamism, vigor and an intellectual approach to aggressive new policies in foreign affairs. The downside was his inexperience in foreign affairs, standing in stark contrast to the vast experience of the president he replaced. He is best known for his call to civic virtue: "And so, my fellow Americans: ask not what your country can do for you - ask what you can do for your country." In Congress the Conservative Coalition blocked nearly all of Kennedy's domestic programs, so there were few changes in domestic policy, even as the civil rights movement gained momentum.
