Post‑election data show that nationwide turnout in the 2024 U.S. presidential election was in the mid‑ to high‑150‑million range, quite close to Jason’s “about 160 million” forecast.

• The University of Florida’s Election Lab (United States Elections Project) estimates 156,302,318 votes cast for president in 2024, with total ballots cast estimated at roughly 156.5–157 million, based on state reports. (en.wikipedia.org)
• The American Presidency Project’s certified popular‑vote totals (77,303,568 for Trump, 75,019,230 for Harris, 2,878,359 for others) sum to about 155.2 million votes for president, consistent with that range once definitional differences are accounted for. (presidency.ucsb.edu)
• A report from the U.S. Election Assistance Commission, summarized by the Associated Press, states that “more than 158 million ballots were counted” in the November 2024 presidential election—this uses total ballots cast as the turnout metric. (apnews.com)

So depending on the exact definition (votes for president vs. total ballots cast), the realized turnout is roughly 155–158+ million, i.e., within about 1–3% of 160 million. Given Jason’s wording (“on the order of 160M,” “about 160 million”), this is reasonably considered accurate, so the prediction is best scored as right.
