Barry Goldwater (1909-1998) was a candidate supported by conservatives against the pro-abortion Nelson Rockefeller in 1964 for the Republican nomination for president. In an upset fueled by the runaway bestseller A Choice Not an Echo, Goldwater won the nomination.
Goldwater was not a social conservative by today's standards, and struggled to win his last election as a U.S. Senator from Arizona. But he was more conservative than Rockefeller in 1964, particularly on economic and foreign policy issues.
Late in life, after Goldwater remarried, he was critical of social conservatives such as Jerry Falwell.
