As of November 30, 2025, Florida has held only one recent statewide abortion-rights referendum: the November 5, 2024 Amendment 4 measure, which would have allowed abortion until fetal viability (around 23–24 weeks) and received about 57% support—below the 60% supermajority required for passage. (en.wikipedia.org) This measure concerned viability/24 weeks, not a 15‑week limit.

Available reporting on Florida’s abortion law and ballot measures shows no subsequent statewide initiative that offers a 15‑week abortion limit as a compromise proposal; instead, the legislature has moved to further restrict the citizen‑initiative process after the near‑pass of Amendment 4, making future amendments harder to qualify for the ballot. (en.wikipedia.org) Because the specific contingency Sacks described—“if they went back with a 15‑week proposal in a future referendum”—has not actually occurred, there is no real‑world result against which to test his claim that such a measure would likely clear 60%. The prediction therefore cannot yet be evaluated for correctness.
