The leading Senate Republican super PAC is launching a substantial $342 million advertising campaign to bolster Republican efforts to retain control of the Senate. This initiative involves securing airtime across eight key battleground states in the upcoming midterm elections.
The Senate Leadership Fund, closely affiliated with Majority Leader John Thune, unveiled the plan on Monday. Their initial ad placements extend significantly into Republican strongholds.
The super PAC has committed $71 million to North Carolina, identified as one of this year’s most hotly contested seats. This is in addition to the $42 million previously pledged in January to support Sen. Susan Collins‘s reelection campaign in Maine.
The spending plan also targets GOP-held Senate seats in traditionally Republican states such as Alaska, Iowa, and Ohio, indicating the super PAC is anticipating substantial political challenges in the midterms.
Notably absent from the list is Texas, where Sen. John Cornyn, backed by the SLF, is competing against state Attorney General Ken Paxton in a May primary runoff. National Republicans are concerned that a Paxton candidacy could put this seat at risk.
The SLF is also investing in three Democrat-held seats while managing a broad battleground defense. They have allocated a total of $107 million for Georgia, where Sen. Jon Ossoff is seeking reelection, and the open Democratic seats in Michigan and New Hampshire.
“The Senate Leadership Fund is in a stronger position than ever to implement an aggressive strategy to protect and grow the Republican Senate Majority,” SLF executive director Alex Latcham stated. “SLF’s historic investment aims to elect strong Republican Senators in crucial battleground states, ensuring Chuck Schumer and his party stay in the minority.”
The largest allocation is in Ohio, with $79 million dedicated to defending a seat previously held by Vice President JD Vance. Jon Husted (R-Ohio) seeks election following his appointment as Vance’s successor, potentially facing former Sen. Sherrod Brown, who narrowly lost to Bernie Moreno in 2024.
North Carolina is the second largest focus, where former Republican National Committee chair Michael Whatley is competing against Democratic former Gov. Roy Cooper. Latcham told The New York Times, which initially reported on the ad buys, that he expects North Carolina to be the most costly race.
Currently, Republicans hold a 53-47 majority in the Senate. Democrats need to gain four seats in November to secure control of the chamber, considering Vance’s tie-breaking vote.
