Right, it would hypothetically make abortion more difficult, but there is no reason to believe that it would save a single life.
Ron Paul OPPOSES a federal ban on abortion and I have seen nothing to suggest that he would support a constitutional personhood amendment. Ron Paul is just like a lot of other pro-choice politicians, he will talk about abortion and say that he hates it, but in the end he will do NOTHING to actually end it.
Ron Pauls legislation would allow it to be illegal in any state that voted to make it illegal.
That, in turn, would save lives.
