Florida abortion rights advocates, who have seen access to the procedure erode in the state and nationally in recent years, reached a major milestone that could shape abortion access throughout the south.

Groups seeking a constitutional amendment protecting abortion on Friday secured enough state-certified signatures by the Feb. 1 deadline to put a referendum on the 2024 ballot.

If successful, voters in the country’s third-most populous state could undo Florida’s abortion bans, keeping access open to thousands of patients throughout the South who travel to Florida from neighboring states — and from as far away as Texas — to avoid more restrictive prohibitions.
