The prediction was: when Democrats next control the presidency, House, and Senate simultaneously (a federal trifecta), Senate Democrats will use the nuclear option to abolish the legislative filibuster.

Key facts:

• The last Democratic federal trifecta occurred during the 117th Congress (January 2021–January 2023), when Democrats held the House, controlled the Senate via the vice president’s tie‑breaking vote, and Joe Biden was president. That trifecta ended on January 3, 2023, before this November 7, 2025 podcast episode. (en.wikipedia.org)
• In the 118th Congress (2023–2025), Republicans controlled the House while Democrats (with independents who caucused with them) controlled the Senate and Biden remained president—so there was no Democratic trifecta. (en.wikipedia.org)
• In the current 119th Congress (2025–2027), Republicans control both the House and the Senate, and Donald Trump is president, so the federal government is under unified Republican, not Democratic, control. (en.wikipedia.org)
• As of late 2025, the 60‑vote legislative filibuster is still in place; recent coverage describes it as an ongoing constraint on ordinary legislation, and debates about ending it are framed as a future possibility, not something that has already happened. (politifact.com)

Because there has been no new Democratic federal trifecta after the date of the prediction, the condition that would trigger the test of Sacks’s claim has not yet occurred. We therefore cannot say whether Democrats would, in fact, abolish the filibuster under those future circumstances.

So the prediction remains untested and is too early to judge.
