..and how is replacing 1 with 50 any better? Rights are rights that shouldn't be trampled by any. This is one of those fundamental flaws of Paul that make him completely unacceptable to Conservatives. To think that he considers fundamental rights something that can be legislated away by any power is disturbing and not in the least bit Conservative. If you think there is big, tyrannical government now, wait until your rights are just considered privileges that can be legislated away at a whim by any little body that sees fit.
(..and if you think moving it from the Feds to the States will in any way keep the feds out, you have another thing coming- see the seatbelt laws & highway financing- the feds will always find a way.)
That would not be the result.
For example, on abortion, many states would ban it.
In contrast, right now the legality of abortion is decided at federal level and so it being legal is forced on all 50 states.
