I would agree with you that they were on the left in the 1960s and that Clinton was a "doper" (he used marijuana but "did not inhale" - LOL!). But neither was a "Red Diaper Baby", which means that neither was born into a family with parents who were Red - at least in so far as we know. That distinguishes those two from O.
However, IIRC, Al Gore’s dad was a Red, or at least a sympathizer, or at least a willing shill, paid off by Armand Hammer. And recall how close he came to being President.
