As the clock ticks on Senate Majority Leader John Thune's ambitious legislative agenda, all eyes are on Senator Lisa Murkowski of Alaska, whose pivotal vote could determine the fate of the sprawling legislative package dubbed the "big, beautiful bill." The Senator has become the center of a frenetic whipping operation as GOP leaders strive to secure her support, especially concerning provisions on Medicaid and food assistance.

In a late-night negotiation marathon, Thune, alongside Finance Chair Mike Crapo (R-Idaho) and Senate Majority Whip John Barrasso, engaged in intense discussions with Murkowski. Emerging from a strategic huddle in Thune's office at 4 a.m., details remained scarce, but the atmosphere was charged with urgency.

Adding to the complexity, the Senate parliamentarian recently confirmed that proposed carve-outs for the Supplemental Nutrition Assistance Program (SNAP) tailored for Alaska comply with the Byrd rule. However, a Medicaid provision critical for Murkowski's state still hangs in the balance, underscoring the precariousness of the bill's passage.

Murkowski has also been vocal about her efforts to amend the rollback of clean-energy credits under the previous administration's climate law, highlighting her commitment to sustainable initiatives.

Thune, projecting cautious optimism, told reporters they were nearing the end of the exhaustive vote-a-rama, with only a few amendments and the final wraparound amendment pending. In a telling sign of the situation's gravity, Thune also convened with Senator Rand Paul (R-Ky.), a staunch opponent of the bill's debt-ceiling hike, in a bid to shore up support.

The bill's trajectory is further clouded by Senator Susan Collins of Maine, who expressed ongoing reservations and a preference for a separate debate on the tax components of the package. Collins' recent setback, when her amendment to increase funding for rural hospitals failed, has not eased tensions.

As Senator Rick Scott (R-Fla.) pushes a controversial amendment to curtail federal payments under the Affordable Care Act's Medicaid expansion—a move supported by the GOP leadership but contentious among some Republicans—the bill's outlook remains uncertain.

What's Next?

Should the Senate pass the bill, it will move to the House Rules Committee, which is scheduled to convene at noon on Tuesday. However, insiders hint at potential delays due to the prolonged Senate proceedings.

Meanwhile, the legislative gears continue to turn as Senate appropriators gear up to tackle the fiscal 2026 government funding bills next week. The House Appropriations Committee is on track to vote on key funding bills by July 10, with an ambitious goal set by Chair Tom Cole (R-Okla.) to finalize all 12 bills by the end of July.

As the Capitol braces for more heated debates, the outcome of the megabill hangs in a delicate balance, with Senator Murkowski's decision poised as a potential linchpin in this high-stakes legislative drama.
