In 1964, Goldwater ran a conservative campaign that emphasized states' rights. Goldwater's 1964 campaign was a magnet for conservatives since he opposed interference by the federal government in state affairs. Goldwater voted in favor of the Civil Rights Act of 1957 and the 24th Amendment to the U.S. Constitution, but did not vote on the Civil Rights Act of 1960. Though Goldwater had supported the original Senate version of the bill, Goldwater voted against the Civil Rights Act of 1964. His stance was based on his view that Article II and Article VII of the Act interfered with the rights of private persons to do or not to do business with whomever they chose, and believed that the private employment provisions of the Act would lead to racial quotas. In the segregated city of Phoenix in the 1950s, he had quietly supported civil rights for blacks, but would not let his name be used.
