Hillary and other Democrats have already spent millions of dollars and hours attempting to force a one-size-fits-all health care plan through Congress. It was a bad idea then, it's a bad idea now. In a country that prides itself on the diversity and individual freedoms of its citizens, it makes no sense to put life-and-death decisions into the hands of a federal bureaucracy. We don't all speak the same language or share the same values or priorities - why should we all be forced into a lowest-common-denominator system?
John McCain has reformed allegedly hopeless causes on a regular basis (perhaps that's why St. Jude still has a place in his campaign). See McCain's comments on health care priorities here.
Thanks to the ever-vigilant Mad Irishman for the tip.
