Voters are deciding whether their state constitutions should guarantee a right to abortion, weighing ballot measures that are expected to spur turnout for a range of crucial races. Passing certain amendments in Arizona, Florida, Missouri, Nebraska and South Dakota likely would lead to undoing bans or restrictions that currently block varying levels of abortion access to more than 7 million women of childbearing age who live in those states. The future legality and availability of abortion hinges not only on ballot measures, as policies could shift depending on who controls Congress and the presidency.
