"The problem is that Roberts' interpretation is not fairly, or even remotely, possible. If the law had been written in the Roberts version -- as a regressive federal tax on the uninsured -- there is no chance it would have passed Congress."
The logic of these statements is flawed. This is pure speculation considering Obama and the Democrats wanted to pass a Healthcare bill no matter what (we have to pass it to find out what's in it). Using the logic that people behaving differently based on the tax/mandate label is not a valid support of the argument that the law was changed. The actions of taxpayers is what dictates how the law is applied to them, not the manner in how they came to the decision of what action to take.
