The FDA is not a hot bed of pro-life insurgent bureaucrats, just the opposite. If they are foot dragging on approval, I'm betting there is some ugly side effects in the background. A rash of dead teens is not the news cycle the FDA wants to be blamed for.
Actually the FDA bureacrats repeatedly recomended the OTC approval of Plan B birth control. The political appointees have blocked it, because of the influence of a small segment of the pro-life movement which has mistaken Plan B birth control for an abortion pill. There are no serious or common side effects.
