Abortion is legal under the Supreme Court. Some states have laws prohibiting or restricting abortion. If you believe that Fed law supersedes state law, then you must also agree that abortion should be legal.
Or to you pick and choose which laws should be governed by the fed or states?
You must know the only way to overturn abortion is through the states?
I see your point, but it's kind of the opposite thing, isn't it? For something to simply not be illegal at the federal level doesn't mean the states can't outlaw it. But for something to be illegal at the Federal level and to have the states undermining it... I mean, the whole point of something being illegal at the Federal level IS TO MAKE SURE it is illegal at the state level. I mean, there is nowhere in the US you can go where you are only under Federal law (that I know of).
To try to make an analogy, imagine you're a child and your parents say, "No soda after 8pm, bed by 9pm" and that's their regular rule. One night they leave you with the baby-sitter, and the baby-sitter decides you are too hyper, so no soda tonight at all. Now, the child can wail "Mom lets me!!" but if the baby-sitter says, "Well, not tonight," it seems a little less egregious than if she said "I don't care what your mom says, let's fire up the bong!!"
Do you see what I mean? The state can be stricter than the Fed, but it shouldn't be looser.
