At least 31 states have adopted laws restricting the ability of doctors to end life support for terminally ill pregnant women, regardless of the wishes of the patient or the family, according to a 2012 report from the Center for Women Policy Studies in Washington. Texas is among 12 of those states with the most restrictive such laws, which require that life-support measures continue no matter how far along the pregnancy is.

31 states are so “pro-life” that they will ignore the pain and suffering of a living adult and overrule her wishes on how she wants to live the last days of her life in order to “protect” a fetus that cannot survive outside the womb.
