EJ Graff is confident that marriage equality will win in the end:
If Kennedy loses his nerve, Congress can and will repeal DOMA—if not this term, then the next time the House, Senate, and presidency are all held by Democrats. And even if the Supreme Court issues a mean ruling on Perry—saying there's no fundamental right to marry and that California voters had every right to pass an amendment yanking equal marriage rights away—the Court will take it back in 15 years, when only ten Southern states are left banning recognition of same-sex marriages. The Court only took 17 years to overturn its ruling upholding sodomy laws in Bowers (which was a knife in the heart at the time, and pretty quickly became an international embarrassment). This one will come just as quickly, or even more so.
