Gruber was needed for the Democrat Members of Congress; House and Senate; and for the Media. ObamaCare was crafted to minimize opposition. They learned from the HillaryCare debacle and bought off the short-sighted Pharmaceutical and Insurance Industries. Both are doomed to destruction under any national healthcare scheme.
He was lying specifically in the construction or writing of Law to benefit a desired end. He was lying to America.
You nailed it. Obama was willing to entrust the fundamental transformation of the best healthcare system in the world to a scam artist. How scary is that?
Gruber references the "tortuous language". It was purposefully obtuse, so that it could neither be clearly understood nor easily refuted. Even challenging it in court has been difficult because the wording can be argued from several different angles (tax, mandate, fine, tax, mandate, fine?).
It was always a moving target and continues to be. How many times has Obama unilaterally changed the law?
