The Heritage Foundation was never elected by the American people. What they think is irrelevant.
Nope. But they authored a proposal centered around an individual mandate to purchase health insurance. It didn't gain any steam in 1989, but it was introduced to Congress in 1993 by Senator Don Nickles (R-OK) and Representative Cliff Stearns (R-FL) as S. 1743 and H.R. 3698.
I invoked the Heritage Foundation on purpose because most people consider that group as the epitome of conservatism.
