"The 1990s are over. Newt Gingrich, who stepped down as House Speaker after the Republicans performed poorly at the polls in 1998, in 2012 lost his comeback bid and the Republican presidential primary. Former representative Bob Barr, the sponsor of DOMA in 1996, in 2009 recanted his support for the bill and said gays should be allowed to marry. Bill Clinton -- who signed it the bill with a statement saying "I have long opposed governmental recognition of same-gender marriages" -- has too. But if that moment of moralism in the mid-90s deserves to be remembered, it's for the lesson that the American people, when they stop being upset about an issue, really let it go. Clinton was impeached over his infidelity, but he hung on to office and became one of the most beloved ex-presidents ever. His party even won seats in the House and Senate the same year his scandal dominated the news, as the public defied political predictions and turned against the moralists instead of the man they accused. As the drumbeat of shifting views of gay marriage continues, each voice affirms gay people as part of the American family, and each senator freshly legitimizes gay Americans as he or she repudiates past views or clarifies new ones. Whatever happens with the Supreme Court, this moment of change and affirmation -- this moment of public evolution -- is having a power all its own."
