Reagan made four successful appointments to the Supreme Court during his eight years in office. In 1981, he successfully nominated Sandra Day O'Connor to succeed Associate Justice Potter Stewart, fulfilling a campaign promise to name the first woman to the Supreme Court. Democrats, who had planned to vigorously oppose Reagan's nominations to the Supreme Court, approved of the nomination of O'Connor. However, the Christian right was astonished and dismayed with O’Connor, whom they feared would not overturn the Supreme Court's decision in Roe v. Wade, which had established the constitutional right to have an abortion without undue government interference. O'Connor served on the Supreme Court until 2006, and was generally considered to be a centrist conservative.
