But Great1, you're assuming that there is a difference between the Republicrats and Demicans and in our three branches of government. The fact is none of our bad policies, i.e. our ever expanding empire and foreign wars, our domestic war on drugs, our welfare/warfare, the increasing, etc., could happen without the votes of Democrats and Republicans. The system is set up to keep outside voices from speaking up. Look at the treatment by the media of persons like Ralph Nader and Ron Paul; people that are truly principled yet are ostracized and vilified by Fox, CNN, NBC, et al.
Both "parties" believe that the other side is just hindering their perfect policies. I tell you now, that regardless if it's Obamacare or Romneycare, our health insurance will increase and both sides will blame each, while government expands. The arguments will be something like, "those racist Republicans and/or Tea Partiers" or "those hippy liberal Democrats" etc... All the while, Big Pharma will generate ever increasing revenues.
The problem with the Commerce Clause is what our government has included in its scope. If we give the current administration the power to regulate healthcare, it certainly is not infeasible for the Supreme Court (all 9 of them) to rule that regulating all business and industry to what the government sees fit is withing the scope of the Federal government. The best and logical thing to do is remove that power from government and return competition to our industry.
