I think the bill is a crap shoot. Giving it to the states and out of the hands of federal day-to-day management is good, getting rid of the mandate and penalty is good. Keeping all the regulations is bad.
However, if the states were to apply pressure, there could be changes made to allow states to reciprocally sell insurance across state lines, paying all health care premiums and expenses pre-tax, not requiring companies to carry pre-existing conditions, etc., it might ultimately be a good thing. It won't be up front though.
