I am definitely pro-life and if a child is conceived through one's own will to have sex than they must deal with the consequences.
However, let's just put it this way: If it God's will for Mourdock to be elected he will be. If it is not God's will he wil not be.
I am certainly not wise enough to presume how much a woman in such a position can endure and I am so glad that decision is not up to me. God did not will for that woman/girl to be raped and the resulting child could end up the joy of her life but such a decision should be between her and God does not wish anyone else to anguish her any further.
Let God decide if his desire to win that race and let that woman/girl make her own decision.
