It's not that they don't care, it's that they care more about what they perceive as wholesale baby murder. Abortion is an extremely important issue in Alabama and to much of the state it is state sponsored genocide on a scale that exceeds anything Stalin or anyone else has committed. It can be difficult for people living in areas where abortion is not seen in this way to understand but in a state like Alabama, to them it really is a matter of being in a constant state of being horrified by the daily murder of thousands of babies. Those who don't see a fetus as being a baby have a hard time understanding beyond the most superficial that this is a deeply held belief by those opposed to abortion. Understanding this point of view on abortion is essential to understanding why so many cannot even conceive of voting for Moore's opponent.
