It is not enough to repeal Obamacare. You need to replace it and that is where the Republicans have failed. This bill is opposed outside Congress (by doctors— the AMA— insurers, Republican governors, and hospitals)— because the replacement will not work and will be worse than Obamacare. On top of that the Republicans want to push the bill through before it is scored for cost, impact on the budget, and numbers of people who will gain or lose insurance coverage.  It is confusing because it pushes responsibility back to the states while giving them federal money— but not enough Federal money so States will need to raise taxes because because they lose Medicaid money, and need to spend to make up for costs that will shift to businesses in their states. Things like discounted group plans at work that do work are uncertain, and the protection for those with pre-existing conditions is a sham.
