Final answer:
The correct answer is option c. promised to pursue a "new frontier.".
Step-by-step explanation:
During the 1960 presidential race, John F. Kennedy promised to pursue a "new frontier." This phrase inspired hope for new possibilities and was open to interpretation by supporters. Liberals saw it as a quest to end racial injustice and poverty, while Kennedy also focused on foreign policy and countering the threat of Communism, especially in Cuba and Vietnam.
Kennedy's support for civil rights was cautious, calculated not to offend white voters. He supported modest spending for antipoverty programs and spoke in favor of civil rights in vague terms. Kennedy's emphasis on foreign policy affected his ability to pass significant domestic legislation.
