Thune-aligned groups unleash historic war chest to defend Senate majority: 'Winning message'

The Senate Leadership Fund (SLF), a group aligned with Senate Majority Leader John Thune, announced raising over $500 million ahead of the 2026 U.S. Senate elections to defend a Republican majority. SLF plans to use its resources and messaging strategy—focusing on issues like crime and inflation—to counter efforts by Democrats. The group stated confidence that combining record funding, strong candidates, and a winning message will allow Senate Republicans to maintain their majority.
