Ok, so let's come to terms with that @Kamaji what is a life worth? OR, John Doe Republican wants to win an election so he'll side step the issue or say that he leans more pro choice than anti-abortion. You can't have it both ways.
Well, Republicans have three choices - (a) figure out how to persuade a majority of voters that their position is correct, (b) realize that there will always be a difference of opinion and that the republican position is the minority position, or (c) get used to being permanently out of power and dancing to the whim of the hard-core leftists in the DNC on every issue.
It is just as simple as that.
And let's be a little more judicious about what sorts of life-ending activities we're willing to accept. We allow people to drive automobiles at high rates of speed despite the fact that we know very well that doing so will result in a certain number of excess deaths every year over the number of deaths that would take place in the absence of strict limits on how fast vehicles can go. A speed limit of 15mph is probably the fastest one could allow cars to go and still avoid those excess deaths.
So, let's turn the question around: how much is one's convenience worth to one in getting to, say, one's destination on a 500 mile trip, given that the cost of that convenience will be a certain number of excess deaths - including of children - that would not happen but for the precedence one gives to one's own convenience.
If reducing the speed limit to 15mph would save the life of just one innocent child, isn't it worth doing?
Also, that "what's a life worth" argument is a very slippery slope that leads very quickly to a lot of the left's preferred political policies, such as making it illegal to use any form of violence in defense of property if that violence could conceivably lead to someone's death. The liberals' favorite argument being: "a person's life is worth a lot more than one's stereo/tv/jewelry/etc, so one should not be permitted to use violence to defend against a thief".
