Cosigning on AggieAXO's post. I've always wondered the same thing about Republicans.
It's been my understanding that "late-term abortion" and "partial birth" abortion were one and the same, and "partial birth" abortion was a term coined by the anti-choice movement to mislead the public into believing that these sort of abortions occurred during the actual full-term birth. (At least, that's what the Senator who wrote me back regarding this issue said.)
Without veering too far, it's easy to search "involuntary sterilization" on Google and look at our nation's horrible history of sterilizing illiterate, poor women of all ethnic backgrounds. One that I can remember involved a 14 year old girl and her sister who was 16. The doctors had their mother sign off on a "pelvic exam" (she couldn't read) which turned out to be a hysterectomy. The doctors' reasoning behind this: they were poor and on government assistance, and were "high-risk" to become pregnant and unable to take care of their children. "Birth control" as far as Margaret Sanger and those women were concerned, was primarily for middle-class white women. Poor white women and black women just needed to be sterilized.
