Turns out, Lady Parts Expert (and Missouri Senate candidate) Todd Akin has a long history of being totally uninformed -- forget about "legitimate rape" for a moment and consider this gem of a statement, from the House floor in 2008:
We have terrorists in our own culture called abortionists. ... You find that along with the culture of death go all kinds of other law-breaking: not following good sanitary procedure, giving abortions to women who are not actually pregnant, cheating on taxes, all these kinds of things, misuse of anesthetics so that people die or almost die. All of these things are common practice, but all of that information is available for America.
Emphasis ours. That is all.
