What counts

The outcome depends on the final Republican seat count in the 120th Congress after the November 3, 2026 election. If Republicans hold fewer than 190 seats, the answer is Yes; otherwise, it is No. Readers often mistake the date of the election for the resolution deadline, but the count includes runoff results and independent caucusing decisions that may extend the timeline to January 4th.
