Obamacare taxes are ALREADY being paid, like the 10% Medical Devices Tax.
The question is the MANDATE
Actually, the question for today is the penalty, not the mandate. No one's arguing that Congress doesn't have the authority to levy a medical devices tax -- it's whether or not the mandate's penalty qualifies as a tax that is today's subject.
If the answer to that is "yes", then the rest of the argument becomes moot, because the USSC will punt until 2014.
