At the 1992 Democratic National Convention that nominated Bill Clinton, Democratic Party leadership made the fateful decision to deny Pennsylvania Democrat Bob Casey Sr. a speaking slot. Casey was a highly successful, two-term governor of one of the nation’s largest states, but Democrats refused to let him address the crowd for one highly specific reason: He was pro-life.

From the moment that the Supreme Court invented a constitutional right to abortion in the 1973 case Roe v. Wade, the Democratic Party began a steady march toward embracing legal abortion on demand. Along the way, it rejected pro-life Democrats such as Casey, with devastating consequences for our nation and our politics.
