Tuesday, Washington D.C.'s City Council overwhelmingly approved a measure to legalize same-sex marriage. Gay rights supporters say the vote comes as a relief after an exhausting year in which the movement experienced as many setbacks as gains. D.C. Mayor Adrian Fenty is expected to sign the measure into law, and commentators say it is unlikely that Congress will try to overrule the city, though it technically has the power to do so. Why Tuesday's vote is proof that gay rights supporters have the momentum in the battle over same-sex marriage.

  • Gay Marriage Goes Mainstream The Politico's Ben Smith calls the vote "a sign that same-sex marriage has really become a quite mainstream Democratic cause, one embraced equally by a Massachusetts court and an urban City Council."
  • Gay Marriage Is Coming, and Conservatives Should Get Used to It Dan Amira of New York Magazine's Daily Intel blog, says the momentum has shifted. "For now, though, it seems that D.C. will soon join Vermont, New Hampshire, Connecticut, Iowa, and Massachusetts as the newest member of the exclusive gay-marriage club," he writes. Embedding a photo of two women in wedding gowns, he gloats. "So get real used to seeing images like the one in this blog post, Sam Brownback (to pick one person who will not appreciate such images)!"
  • Finally, Some Good News Doug Mataconis of Below the Beltway says "This is one advance that doesn't look like it will be rolled back anytime soon. Good."
  • Momentum Eli of FireDogLake says the Senate docket in New Jersey suggests the Garden State could be next. New Jersey, he says, "is nowhere near as done a deal as DC, but it's a helluva lot closer than it was a week ago, when there were no plans to vote at all."
  • Don't Count Your Chickens... Brian Moylan of Gawker is more cautious. "D.C. seems poised to legalize gay marriage. Let's see what Congress says about that."
  • A Note on Marion Barry's Nay Vote At The Atlantic, Ta-Nehisi Coates says the nay vote of city council member and former D.C. mayor Marion Barry lends a sober note to Tuesday's vote. Why? Because "it's worth noting that there is very little difference between Barry and Barack Obama on gay rights. Barry may even be more progressive."
