Any day now, the New Mexico Supreme Court may grant same-sex couples the right to get married.
At this point, such a ruling may not seem like such a big deal. Prior to last year's elections, gays and lesbians had a civil right to marry in only six states. Now, they have it in 16.
"This year represented the true tipping point," says Eric Marcus, author of Making Gay History. "We've reached a moment in history where it's very difficult, if not impossible, to go back."
