I liked this quote in one of the comments: "Republicans are far more socialist than Democrats. Just because they want to redistribute the wealth upwards does not make it any better."

In our three-branch system of government what the Supreme Court says is the very definition of what is constitutional. I don't always agree with their opinions (see Citizens United) but it is what it is, and Rand Paul saying otherwise is like him proclaiming that white is black, the sun rises in the west, or pi=3.
