I dont think it's a good thing to start on because of the internet. It can be a double edged sword for him in the not so red states.
As for Ron Paul on the issue...
This is the entire abortion argument IMHO.
Pro-choicers say that when the baby is still in the mother it does not have any rights and making abortion illegal is taking AWAY the rights of the mother.
Pro-lifer's say that a baby DOES have rights and that killing it is actually taking away IT's right to live.
So from Ron Paul's point of view abortion IS a denial of Liberty and he is standing behind it just like he stands behind ever issue and that's that he is a protector of Constitutional rights (including those of unborn babies) 100%.
Regardless if you are pro-choice or not Ron Paul made a very good point regarding the matter that I have never really heard before:
People like to claim that before a baby is born it's not really a person and doesn't have any rights so if you kill it before it's born then that's your decision and there should be no consequence for your actions.
However, if a doctor screws up and causes your baby to die before birth he is held COMPLETELY responsible for killing the child. If a woman is murdered while pregnant you are charged with TWO counts of homicide.
Why is that if it's YOUR choice to abort that suddenly a baby isn't a baby any more and is just a bunch of cells but when you actually WANT to have it those "lump of cells" magically become important?
I'd like to see someone take a woman that earlier in her life had an abortion but now is pregnant again and wishes to keep the child. I'd love to see her response if the doctor came in and told her "Oh I'm sorry to tell you this but that medicine I gave you earlier today accidentally killed your baby. I see you've had an abortion before though so I'm glad to know it won't really bother you. Good luck next time."
If killing a child while it is inside you is truly ok then there should be NO difference in feeling regardless if you wanted to have it or not. Since this is NOT the case there is obviously something very wrong with doing so.
If it's just a bunch of unimportant cells I'd like to see a mother that just aborted her child actually have to look at the remains of the child dead in the bowl and then be forced to carry those remains herself to the place in which they are disposed/incinerated.
If a girl could do that without breaking down and crying then you might could convince me abortion is ok. Until then...meh
Here is a good vid of Dr Paul discussing the issue in depth.
