The marriage debate is entering a new phase. As recently as 1996, a Gallup survey found that 68 percent of Americans opposed civil marriage rights for same-sex couples. On May 8 of this year, Gallup released a report which found that only 48 percent were opposed to same-sex marriage while 50 percent were in favor. The next day, in an interview with Robin Roberts of ABC News, President Barack Obama announced that he too favored the legal recognition of same-sex marriage, a move that delighted social liberals, many of whom believed that the president’s previous tepid opposition was rooted in political concerns rather than real conviction.
