Supreme Court Upholds Oregon Suicide Law

The Supreme Court upheld the Oregon assisted suicide law. I was afraid after Raich that we would just end up abolishing state governments and let the Feds take over and homogenize the country. What's interesting, though, is the most staunch defender of state's rights, Clarence Thomas, was on the other side of this one, voting to negate the Oregon law. It seems like the two cases are very similar and I don't know how Thomas can reconcile his conflicting votes.
