As Jeremy points out, it seems like we hear about a new lawsuit in a new state challenging an anti-gay marriage ban every day. That’s because there are indeed quite a few of them:

Keeping track of the lawsuits requires a scorecard: The Human Rights Campaign counts 57 cases in 27 states, while Freedom to Marry, another advocacy group, counts 61 cases in 30 states. All told, the cases have nearly 550 plaintiffs.

And according to this graphic, there are only four states left that ban marriage equality, and whose bans have gone unchallenged:

Somehow I doubt those bans will go unchallenged much longer, though. So come on, Montana, Alaska and the Dakotas! It’s time to get to filing!
