This is my assumption:
Rape that's illegitimate: Sex between a couple that may be legally considered to be rape (ie: boyfriend/girlfriend ages 17 and 19 - depending on the state)
Legitimate rape: forced sex
That's my take and what I think he meant. But that's just my own assumption. I have not heard the man's explanation.
What he said about pregnancies cannot happen as a result of rape was way over the top.
He needs to go. It may very well be a choice of him or Romney in that state which means it's Akin or Obama.
I suppose it IS a bit like saying a woman can’t be raped because a woman can move it around.
