In case you forgot what Partial Birth Abortion is – here's a summary with illustrations courtesy of Priests for Life:
The Partial Birth Abortion Procedure
Guided by ultrasound, the abortionist grabs the baby's leg with forceps.
The baby's leg is pulled out into the birth canal.
The abortionist delivers the baby's entire body, except for the head.
The abortionist jams scissors into the baby's skull. The scissors are then opened to enlarge the hole…
The scissors are removed and a suction catheter is inserted. The child's brains are sucked out, causing the skull to collapse. The dead baby is then removed.
