National Heath care might seem like bad voodoo, but the government is already pay for over 1/2 of all medical spending in the US yet medical bills are still the leading cause of bankruptcy in the US. Most countries with a national heath care system spend less money per person and relative to their GDP than we do now and we still have a crappy patchwork. When a hobo shows up at a hospital he is going to get treatment and we are going to pay his bill but I still need to buy expensive medical insurance.
PS: I am a consultant working for the DoD and I have saved the US taxpayer millions. If you had any idea what games where being played you would probably also vote Democrat because it saves you money.
