Background
John Thune became Senate Majority Leader in January 2025, succeeding Mitch McConnell. In April 2026, Thune refused to deploy the nuclear option to lower the Senate's filibuster threshold from 60 to a simple majority for the SAVE Act, publicly stating he lacked sufficient votes within his own Republican conference to pass the bill even at a 51-vote threshold . Senator Lisa Murkowski had already voted against cloture, and other Republican moderates were not reliably committed.
Thune, a South Dakota Republican first elected to the Senate in 2004, built his career as a McConnell loyalist and an institutionalist resistant to rule changes that could undermine Senate traditions. His refusal on the nuclear option is consistent with his career position, but it placed him in direct conflict with House Republicans and the Trump administration who had wanted the SAVE Act passed before the 2026 election cycle.
The Senate shifted strategy to a performative marathon floor debate, designed to put Democrats on the record voting against citizenship verification requirements rather than to pass the bill. Thune's decision reflects a recurring tension in his leadership: he must manage a conference that includes both Trump loyalists demanding aggressive procedural manoeuvres and institutionalists like Murkowski and Collins who resist them.
