Of all places, I found this at Forbes.com: Congress Passes Socialized Medicine and Mandates Health Insurance - In 1798, by Rick Ungar. First, let's jump to the conclusion:
The moral to the story is that the political right-wing has to stop pretending they have the blessings of the Founding Fathers as their excuse to oppose whatever this president has to offer.
History makes it abundantly clear that they do not.
Now, just the opening paragraphs, to give you the meat of this wonderful, and timely, historical illustration.
In July of 1798, Congress passed – and President John Adams signed - "An Act for the Relief of Sick and Disabled Seamen." The law authorized the creation of a government operated marine hospital service and mandated that privately employed sailors be required to purchase health care insurance.
Keep in mind that the 5th Congress did not really need to struggle over the intentions of the drafters of the Constitutions in creating this Act as many of its members were the drafters of the Constitution.
And when the Bill came to the desk of President John Adams for signature, I think it’s safe to assume that the man in that chair had a pretty good grasp on what the framers had in mind.
Ungar quotes the recent State of Florida, et al. vs. HHS filing against the Patient Protection and Affordable Care Act to show how contrary to actual American history today's conservatives are.
