Nathan Newman nails the Faux-Federalist Supremos:


One more example of the conservatives on the Court wanting to preempt state law where they can weaken protections for workers and consumers. In a decision yesterday, the Supreme Court upheld by 5-4 the ability of state governments to regulate some HMOs, but the conservatives in the minority deplored the "disparate state laws" that would undermine the federal goal of "uniformity in this area."
...Let's be straight about it; the conservatives aren't against federalism. They are just against laws they don't like and use federalism selectively to bash local or federal laws as needed.
