The Texas supreme court closed out 2023 by blocking an abortion during a medical emergency, forcing a woman to flee the state. Just days before Christmas, Wisconsin justices struck down the state’s GOP-drawn gerrymanders. So far this year, Montana’s supreme court has stepped in to protect voting rights, while a decision in Alabama threatened in vitro fertilization treatments.

In each of these states, unlike at the federal level, voters chose who sits on the bench and which judges get to dictate such profound consequences. And the 2024 elections may now reshape who holds power on supreme courts across the country.

Thirty-three states have elections for their high courts this year; some have as many as five or six seats on the ballot. In total, 82 seats are up for voters to decide.

These races to decide the composition of state courts could potentially shift the outcome in high-stakes cases that are already in the legal pipeline on everything from the rules of direct democracy to the fate of reproductive rights.

Michigan and Ohio are the two states where a supreme court’s partisan majority could flip outright. Democrats are defending a narrow edge in Michigan; the GOP is doing the same in Ohio.

But the 2024 elections may also affect the ideological balance of other supreme courts, starting with Kentucky, Montana, North Carolina, and Texas. Some of these states hold nonpartisan races where judicial candidates are not affiliated to political parties; but those courts still tend to have liberal, moderate, and conservative wings, and parties and other groups often get involved in their elections, sometimes pouring in huge amounts of money.
