Maine and Maryland made history on election night by becoming the first states to legalize same-sex marriage by a popular vote.

An hour ago, Washington officially joined in by confirming the passage of its own marriage equality measure, Referendum 74.

Minnesota also contributed to this election's history-making by becoming the first state to defeat a constitutional amendment to ban same-sex marriage.

To put the four-out-of-four sweep in perspective, before this year, marriage equality made 32 ballot appearances and lost every single time.

That's a big fucking deal. Particularly when you take into account that Maine voters rejected a same-sex marriage bill just three years ago.

Needless to say, celebration was well warranted, and cameras were happily on hand in three of the four states to capture the moment each marriage equality measure passed (or, in the case of Minnesota, the moment the anti-marriage-equality measure failed).
