Early and sustained engagement with key congressional leaders is critical, starting within the first 15 days of Phase 1 (Month 1), where the White House Office of Legislative Affairs (OLA) briefs chairs and ranking members of key committees like House Oversight and Senate Judiciary. The initiative should be framed as a bipartisan opportunity for economic growth, emphasizing $100-200 billion in annual cost savings (per OMB estimates) and job creation, with biweekly updates to maintain momentum. Supporters like Rep. James Comer (R-KY, House Oversight Chair) would champion this as a way to curb government overreach, appealing to his Kentucky manufacturing and energy constituents, while Sen. Ted Cruz (R-TX, Senate Judiciary) would push for aggressive energy deregulation. Opponents like Rep. Jamie Raskin (D-MD, Oversight Ranking Member) would argue it risks dismantling environmental and labor protections, demanding robust justifications, and Sen. Elizabeth Warren (D-MA, Senate Banking) would oppose financial deregulation, citing risks to consumer protections. Supporters are likely to win initial House support (e.g., 220-215) due to Republican control, but Senate passage (60% likelihood) hinges on swaying moderates like Sen. Joe Manchin with concessions like preserving key safeguards. Early bipartisan briefings and targeted messaging are essential to counter progressive resistance and avoid filibusters.
