If it's true that today's District v. Heller ruling is the first time in U.S. history that the Supreme Court has has directly ruled on meaning of the Second Amendment, it also seems likely to be the last. The battle has carried on for decades in lower courts, but those cases too are likely to be cut short, if not cut off altogether.
But what about the cultural/moral argument? I noted in my previous Next Right post that the left has largely acquiesced to gun rights. They may do so grudgingly, but for all intents and purposes they've given up. Except... that's not what I found on some of the most influential leftroots blogs.
Instead, I found significant agreement with the ruling. Not just that, but matter-of-fact statements of support for an individual right that would have been unthinkable even five years ago.
