With New Hampshire now on board, there are 6 1/2 states that have (or will have by fall) lawful gay marriage. Of course I include California, where same-sex marriage is unconstitutional except for the 18,000 marriages that were entered into between the time of the Supreme Court's opinion in In Re Marriage Cases and the passage of Proposition 8.
In fact, we probably have more same-sex marriages in a state that prohibits them than even the reigning champion, Massachusetts -- and that's true even if you assume that a full 25% of our marriages were of out-of-state couples, an extremely generous margin.
To quote Shakespeare, "The course of true love never did run smooth," and the legal recognition of same-sex partners is following as erratic and meandering a path as any comic plot Shakespeare could have devised or stolen. The blessing is that we now have good reason to believe these preposterous incongruities are worth laughing about, rather than crying over.
