Don Surber's blog about the commerce clause and possible Obamacare ruling speculates that we may not just see the chucking of the mandate, or even the entire legal package. The expanded interpretation of the commerce clause, allowed solely for the Civil Rights Act, will be limited by the majority opinion.
A byproduct? You can bet that advocacy groups will paint this as the first step in the return of Jim Crow, as if that was even possible.
Some speculate that the striking down of Obamacare will help the president's re-election because it will diminish zeal among his opponents. As if rising debt and gas prices are not stimulation enough.
