Anti-abortion 'personhood' measure fails to make Colo. ballot

But the group noted GOP presidential candidate Mitt Romney has said he would support personhood proposals, which go too far even for many conservatives. Voters in Mississippi rejected a personhood proposal last year after Gov. Haley Barbour (R) said he had reservations about the approach.

 “The defeat of ‘personhood’ state constitutional amendments all across the country — from Colorado and Ohio to Mississippi and Oklahoma — sends a clear warning to Mitt Romney: health care decisions should be left to a woman, her family, her doctor, and her faith — not politicians. This is just one more example of how out of touch Mitt Romney is with women and the majority of Americans when it comes to women’s health," Planned Parenthood Action Fund President Cecile Richards said in a statement.

Personhood proposals would define life as beginning at the moment of fertilization. While that would outlaw abortion, it also would prohibit many forms of contraception and could limit women's access to procedures like in vitro fertilization.
