Abortion rights advocates lost on Florida, Nebraska and South Dakota ballot measure but prevailed in seven other states, including Missouri, where an amendment clears the way to undo one of the nation's strictest bans.

The Associated Press projected passage of Amendment 3, an amendment that will enshrine abortion-rights protections in Missouri's constitution.

A ballot amendment enshrining reproductive rights in the State Constitution would void one of the strictest abortion bans in the country.
