"Forcible rape" in the new abortion legislation

Two recent posts--one at The Huffington Post and one at the Washington Post's PostPartisan blog--address the question of whether the proposed federal legislation, which limits abortion funding to cases of "forcible rape," is intented to and should distinguish among the various situations currently combined in the rape category by modern codifications, including for example rapes accomplished as a "result of a woman being drugged, drunk, mentally disabled or date rape." Thanks to Ken Simons for calling these to our attention.
