Too many of the supposedly "conservative" justices have morphed into liberals. It wasn't more than a year ago that they decided that a city can take your business and give it to your competitor.
So you think they can roll back 60 years of socialism in 6? My, you are an optimist.
I think they could do it overnight in a Constitutional convention. Another option we might have is to have a amendment to allow states to secede and/or to have a procedure for ejecting states from the union.
But I don't see the pendulum swinging any other way but left. We are moving towards more socialized medicine. The Supreme Court makes noises about modeling our laws to be consistent with European laws. The borders are still wide open and Bush wants to legalize the illegals which will only invite more. We don't have much time to fool around.
I'm not an optimist. I'm a realist who sees that our options are getting more and more limited.
