<h1>Budget reconciliation emerges as central legislative tool as Republicans weigh single versus multiple bill strategies to advance priorities.</h1> Republican leaders and the president elect are negotiating whether to pursue a single comprehensive legislative package or multiple bills, reflecting narrow GOP majorities and mixed signals from the president elect. The central procedural focus is the use of budget reconciliation to pass measures by simple majority in the Senate without filibuster, a mechanism that is procedurally strict and time consuming but can enable passage of tax and fiscal legislation; sequencing and risk increase if reconciliation is used more than once. Substantive priorities include tax changes, border security and deportation, program cuts, energy development, and defense funding.
