At approximately 10:00 today, in a vote of 5-4 Chief Justice Roberts, siding with the liberal Justices, read that the Individual Mandate under the Affordable Care Act (Health Reform) is constitutional not as interstate commerce but as a tax.

For people in favor of the law, this is an obvious win in their direction. However, people not in favor of the law, the President, or continued government over-reach could see this as helpful for Romney's presidential bid in November.
