Back during the very first vote on partial birth abortions, I believe in 1994, there were 10 of the nation's highest respected doctors appearing before the Senate committee. A Republican Senator (Hatch, I believe) asked something very similar to, "Under what circumstance would a woman's life be in danger if a tri-semester fetus were removed from the mother alive instead of killing it first?"
The question went down the line to each of the 10 doctors and each one responded, "NEVER!"
Yep.
C. Everett Coop, the Surgeon General under Ronald Reagan, a lifelong obgyn, said that of the tens of thousands of babies he delivered in his career, there wasn't one that required killing the child to save the life of the mother.
