Iowa just did what?

In a ruling that I'm still trying to wrap my mind around, the Iowa Supreme Court ruled that the state's ban on gay marriage violates homosexual's equal protection under the law. Seriously, Iowa is a more progressive state than California? While I'd be surprised if the fundies didn't try to work a constitutional amendment overturning the court's decision, I'm very, very glad to see that even a state like Iowa can realize that equal protection applies even to groups that may be unpopular.
