Yesterday, CNN quoted a Cain 'adviser' on the abortion issue, saying that Cain follows the GHWBush model--in effect, kill babies for the sins of their fathers (rape and incest). He also uses the 'life of the mother' exception, which is most often morally acceptable under the principle of double-effect. (However, there are VERY few cases where this is necessary.)
Well, that was yesterday.
One has to give more weight to Cain's own statement than that of his 'adviser.' But it would be a helluvalot easier if they were on the same damn page from one day to the next.
Unless Cain is deliberately following the Romney School of electoral politics, of course.
