In 2009, the University of Notre Dame set off months of intra-Catholic controversy by inviting a champion of abortion rights to deliver the school’s commencement address. When the day arrived, President Obama skillfully deflated the tension. He extended a “presumption of good faith” to his pro-life opponents. Then he promised Catholics that their pro-life convictions would be respected by his administration. “Let’s honor the conscience of those who disagree with abortion,” he said, “and draft a sensible conscience clause, and make sure that all of our health-care policies are grounded not only in sound science but also in clear ethics, as well as respect for the equality of women.”
Catholics, eager for reassurance from a leader whom 54 percent of them had supported, were duly reassured. But Obama’s statement had the awkward subordinate clauses of a contentious speech-writing process. Qualifications and code words produced a pledge that pledged little.
