I thought this summed it up nicely:

Was today's Supreme Court Obamacare decision a win for conservatives or a loss? It depends on what you were rooting for.
If you were above all interested in the bill being struck down, it was mostly a loss. On the other hand, if you were more concerned about the qualitative expansion in the power of the government that the bill represented, it was definitely a win.
First, the Roberts Court put real limits on what the government can and cannot do. For starters, it restricted the limits of the Commerce Clause, which does not give the government the power to create activity for the purpose of regulating it. This is a huge victory for those of us who believe that the Constitution is a document which offers a limited grant of power.
Second, the Roberts Court also threw out a portion of the Medicaid expansion. States have the option of withdrawing from the program without risk of losing their funds. This is another major victory for conservatives who cherish our system of dual sovereignty. This was also a big policy win for conservatives; the Medicaid expansion was a major way the Democrats hid the true cost of the bill, by shifting costs to the states, but they no longer can do this.
Politically, Obama will probably get a short-term boost from this, as the media will not be able to read between the lines and will declare him the winner. But the victory will be short-lived. The Democrats were at pains not to call this a tax because it is inherently regressive: the wealthy overwhelmingly have health insurance so have no fear of the mandate. But now that it is legally a tax, Republicans can and will declare that Obama has slapped the single biggest tax on the middle class in history, after promising not to do that.
Conservatives have a shot at getting the best of both worlds: having the Supreme Court use Obamacare as a way to limit federal power while also using the democratic process to overturn the law. I didn't think we could have one without the other, but now maybe we can.
If Obama loses in November, that is…
