Certain portions of it will likely never be repealed.
The “Junior can stay on dad’s plan till age 26” provision won’t ever be repealed.
The “they have to take you and your pre-existing condition” clause seems pretty repeal-proof.
In states that were stupid enough to expand Medicaid there are tens of millions of new recipients who will be hard to discharge.
Other than that though, plenty of room to work.
I doubt much of anything will be repealed until a particular item has cost millions to billions and it’s done as a last resort. 0care will be a money pit and become nothing but socialized medicine.
