Republicans hold a 53-47 Senate majority following the 2024 elections, enabling use of the reconciliation process to advance fiscal legislation with a simple majority vote rather than facing the filibuster. A budget resolution adopted earlier in 2026 set instructions for committee submissions, leading to passage of one major reconciliation package in June focused on border security and related appropriations; a third bill remains possible before year-end if additional instructions are approved. The November 2026 midterm elections, which include 35 Senate seats, introduce uncertainty over continued majority control and could shift procedural dynamics for any remaining measures. Key variables include committee markups, vote thresholds within the caucus, and alignment with House action or presidential priorities.
