From the 1960 platform:
6. "The right to adequate medical care and the opportunity to achieve and enjoy good health."
Illness is expensive. Many Americans have neither incomes nor insurance protection to enable them to pay for modern health care. The problem is particularly acute with our older citizens, among whom serious illness strikes most often.
1968:
The best of modern medical care should be made available to every American. We support efforts to overcome the remaining barriers of distance, poverty, ignorance, and discrimination that separate persons from adequate medical services.
During the last eight years of Democratic administrations, this nation has taken giant steps forward in assuring life and health for its citizens. In the years ahead, we Democrats are determined to take those final steps that are necessary to make certain that every American, regardless of economic status, shall live out his years without fear of the high costs of sickness.
1976:
We need a comprehensive national health insurance system with universal and mandatory coverage. Such a national health insurance system should be financed by a combination of employer-employee shared payroll taxes and general tax revenues. Consideration should be given to developing a means of support for national health insurance that taxes all forms of economic income. We must achieve all that is practical while we strive for what is ideal, taking intelligent steps to make adequate health services a right for all our people.
1984:
It will not be enough to say that our nation must offer equal access to health carewe must put comprehensive health care within the reach of all of our citizens, at a price all can afford.
1992:
All Americans should have universal access to quality, affordable health carenot as a privilege, but as a right.
And so on.
