The Idaho Senate  has voted 24-10 to pass legislation banning abortions once a fetus has reached 20 weeks. Republican Senator Chuck Winder's measure now goes to the House for debate. If it becomes law, Idaho could follow Nebraska in banning abortions after 20 weeks despite a state attorney general's opinion that found the bill is unconstitutional. The bill is also advancing amid doctor concerns that it could force women to deliver babies suffering from rare-but-deadly diseases that leave them little chance of survival outside the womb. Democratic Senator Diane Bilyeu, of Pocatello, argued the legislation "lets Big Brother decide what's best for our families." But Winder says his bill is about new science that shows a fetus 20 weeks after fertilization will suffer during an abortion.
