Second, in writing his case, Roberts forces everyone to deal with the issue as a political, not a legal issue. In the past twenty years, Republicans have punted a number of issues to the Supreme Court asking the Court to save us from ourselves. They can’t do that with Roberts. They tried with McCain-Feingold, which was originally upheld. This case is a timely reminder to the GOP that five votes are not a sure thing.
Third, while Roberts has expanded the taxation power, which I don’t really think is a massive expansion from what it was, Roberts has curtailed the commerce clause as an avenue for Congressional overreach. In so doing, he has affirmed the Democrats are massive taxers. In fact, I would argue that this may prevent future mandates in that no one is going to go around campaigning on new massive tax increases. On the upside, I guess we can tax the hell out of abortion now. Likewise, in a 7 to 2 decision, the Court shows a strong majority still recognize the concept of federalism and the restrains of Congress in forcing states to adhere to the whims of the federal government.
