D.C. is starting to consider actively allowing same-sex marriage. This process is a wee bit more complicated than usual, because D.C. is not a state. Any bill that the city council passes must be approved by Congress. There'll be a fight, but I don't think it'll be much of one. D.C. already recognizes same-sex marriages performed in other states (as does New York), and its corruption level hasn't changed much since, although, to be honest, that's not really saying much.
But, yes. Go, D.C. Democrats!
