Voters backed abortion rights, but the state judges they elected might not

In November, Montana voters safeguarded the right to abortion in the state's constitution. They also elected a new chief justice to the Montana Supreme Court who was endorsed by anti-abortion advocates.

That seeming contradiction is slated to come to a head this year. People on polar sides of the abortion debate are preparing to fight over how far the protection for abortion extends, and the final say will likely come from the seven-person state Supreme Court. With the arrival of new Chief Justice Cory Swanson, who ran as a judicial conservative for the nonpartisan seat and was sworn in Jan. 6, the court now leans more conservative than before the election.

A similar dynamic is at play elsewhere. Abortion rights supporters prevailed on ballot measures in seven of the 10 states where abortion was up for a vote in November. But even with new voter-approved constitutional protections, courts will have to untangle a web of existing state laws on abortion and square them with any new ones legislators approve. The new makeup of supreme courts in several states indicates that the results of the legal fights to come aren't clear-cut.
