In case you hadn't realized that this debate is decades old:
Democrats frequently say that they have been fighting to bring us national health care ever since FDR, and that is true. The United States has had an even dozen president since FDR (inclusive), and none has signed a national health care plan into law. Democrats don't seem to realize that there's a reason so many presidents and so many Congresses have decided not to take over the health care system.
It's because our system - warts and all - is the world's best. Clearly, it can be improved significantly - but not by putting government in charge. What Washington must do is get out of the way. Real reform will put patients in closer contact with their doctors, and give them control of key health care decisions.
Or to put it another way, keep your laws off my body.
