Senate Republicans have already enacted two reconciliation packages this Congress—a major 2025 tax and domestic policy bill and a June 2026 $70 billion immigration enforcement measure—leaving limited procedural room and political appetite for a third. House passage of a FY2027 budget resolution in July set up instructions for roughly $95 billion in defense, agriculture, and election-security provisions, but Senate Majority Leader John Thune has deferred action on a matching resolution until after a short-term continuing resolution clears the September 30 funding deadline. Internal GOP divisions over spending offsets, amendment exposure before the November midterms, and competing priorities have stalled momentum, with key senators signaling resistance to another party-line vehicle this session. Any Senate vote on the budget resolution or resulting reconciliation bill would occur after the August recess and remain subject to vote-a-rama dynamics and potential holds.
