If it is a TAX, it must be apportioned equally. If it is a Tax it has to originate in the House, not the Senate like it did. It's an illegally originated Tax and does not have enforcement of law behind it. The first person they arrest for not paying this tax will beat it in court and the the Tax will be abolished. Mike Lee had a great explanation on this subject during the filibuster. You still can't force someone to buy something they don't want, but you can tax legally.
The pain of Obamacare during its implementation will be quite painful and that is somewhat Roberts fault, but in the end I think the purpose is to teach us a lesson we will never forget.
