Not sure where you get that from. I think he'll be a vast improvement over O'Connor. But even if he is what you think that is good enough for me. I don't care much for "hot button conservative social issues." It bothers me more that the Government can take my home then that Roe v Wade is the law of the land. Although I disagree with them both.
On Kelo I think he would have been in the dissenting opinion.
O'Connor was very good on property rights and most state rights issues.
I see Roberts being solid in this area. But remember that will leave us with Kennedy being the swing vote who is horrible in this area. We have to wait for one of the liberal justices to retire to get the court righted in the right direction in this area.
