On June 14, 1967, Ronald Reagan signed the Therapeutic Abortion Act, after only six months as California governor. From a total of 518 legal abortions in California in 1967, the number of abortions would soar to an annual average of 100,000 in the remaining years of Reagan’s two terms — more abortions than in any U.S. state prior to the advent of Roe v. Wade. Reagan’s signing of the abortion bill was an ironic beginning for a man often seen as the modern father of the pro-life movement. How did this happen? When the issue surfaced in the first months of his governorship, Reagan was unsure how to react. Surprising as it may seem today, in 1967 abortion was not the great public issue that it is today. Reagan later admitted that abortion had been “a subject I’d never given much thought to.” Moreover, his aides were divided on the question. Reagan began to vigorously study the issue and the Therapeutic Abortion Act. He asked his longtime adviser and Cabinet secretary Bill Clark — a devout Catholic who had contemplated the priesthood — for counsel. “Bill, I’ve got to know more — theologically, philosophically, medically,” Reagan confided. Clark loaded up the governor with a box of reading materials, which he took home and read in semi-seclusion. Edmund Morris later said that, by the time the Therapeutic Abortion Act reached his desk, “Reagan was quoting Saint Thomas Aquinas.” Years later, Reagan remarked that he did “more studying and soul searching” on the issue than any other as governor. Nonetheless, he signed the bill. Reagan and his staff calculated that if he vetoed the bill, his veto would be overridden by the state legislature. Therefore, he decided to do what he could to make the bill less harmful, arguing for the insertion of certain language that eliminated its worst features and allowed for abortion only in rare cases — such as rape or incest, or where pregnancy would gravely impair the physical or mental health of the mother.
