The US Supreme Court is currently considering arguments for and against gay marriage. In the prognosticating about what was going to happen, and given John Roberts' willingness to cave at the last minute on Obamacare, I think Pax Dickinson's view is probably a fair bet:
"My guess is that SCOTUS will arbitrarily legalize gay marriage in all 50 states. Cthulhu only swims left."The latter part is a rather reliable prediction, especially in the long run, but it's a somewhat noisy predictor for any particular Supreme Court decision. Cthulhu swam right, at least temporarily, on the question of the Second Amendment. Maybe gay marriage will break the same way, although I wouldn't bet on it.
That said though, there's someone who called all this much earlier, saying that the Supreme Court was going to impose gay marriage on the country. They made this prediction way back in 2003, in fact.
See if you can guess who it was (answer below the fold).
