When the U.S. Supreme Court repealed in June a woman’s constitutional right to an abortion, Wisconsin’s 1849 law that bans the procedure except when a mother’s life is at risk became newly relevant.

Republicans in the Legislature blocked an attempt by Democratic Gov. Tony Evers to overturn the law. Yet there’s disagreement inside the GOP over how to move forward when they return to the state Capitol in January.

The state’s powerful Republican Assembly speaker, Robin Vos, supports reinforcing the exception for a mother’s life and adding protections for instances involving rape and incest. Others, including GOP state Rep. Barbara Dittrich, say the law should stay as it is, without exceptions for rape and incest.

For decades, Republicans like Vos and Dittrich appealed to conservative voters — and donors — with broad condemnation of abortion. But the Supreme Court’s decision is forcing Republicans from state legislatures to Congress to the campaign trail to articulate more specifically what that opposition means, sometimes creating division over where the party should stand.
