WASHINGTON (AP) — Montana voters chose to protect the right to an abortion in their state constitution. The ballot initiative sought to enshrine a 1999 Montana Supreme Court ruling that said the constitutional right to privacy protects the right to a pre-viability abortion by a provider of the patient’s choice. Though there’s no defined time frame, doctors say viability is sometime after 21 weeks. The Associated Press declared the amendment was approved at 6:01 a.m. EST Wednesday.
