Nonsense, they do that all the time. A large part of Obamacare and most other large bills modify existing law. New laws simply over-write previous laws.

I'm not saying it can't/doesn't happen. I'm saying it hinders such laws, if not stops them. Obamacare was achieved only after an ENORMOUS fight, at tremendous cost (politically and financially), and is still embattled upon the verge of being overturned. Point is that filling a void is easier than having to empty one first.
