A day or two ago, after the US Congress declined to do anything to stop marriage equality in the District, same-sex marriage opponents made a last-ditch attempt: they asked the US Supreme Court to step in and send the matter to a popular vote.
Chief Justice Roberts responded with a three-page opinion in which he said that now is not yet the right time to appeal to SCOTUS. At some future point, after a lower court ruling, the Supremes may yet get involved, but not right now.
Which means that, starting in about four and a half hours, same-sex couples can apply for marriage licenses in Washington, DC.
Those couples who apply today will be able to obtain marriage licenses on Tuesday, March 9, assuming all goes well.
Exciting! Congratulations to all who'll be getting married!
