Andrew Sullivan, who, by the way, is largely shutting down his blog for a couple of months, relays to conservatives this question from a friend:
Good question. In fact, Viewpoint will go one better. Why should this be a matter of one or the other? Why shouldn't conservatives be arguing for both amendments? If the marriage amendment is necessary to protect marriage, and it may well be, surely an anti-abortion amendment is necessary to protect the lives of unborn children and is long overdue. It doubtless would not have been possible to get such an amendment through congress before now and may not be possible to get one passed even now, but shouldn't the arguments for it at least be raised?
That some conservatives have gone on record calling for the marriage amendment, but none appear to be interested in a constitutional corrective for Roe v. Wade, a decision many believe to be a clear case of judicial overreach that has resulted in the sacrifice of millions of lives, seems at best a little inconsistent.
