Republicans are increasingly concerned that North Carolina and Georgia, once viewed as crucial to preserving their Senate majority, are becoming difficult contests. Rep. Mike Collins is challenging Georgia Sen. Jon Ossoff, while Michael Whatley is running against former Gov. Roy Cooper in North Carolina; both candidates trail in polls and face campaign questions. A Republican defeat in North Carolina, which President Donald Trump won three times, would give Democrats one of the four Senate victories needed to regain control. Old North Action cut its North Carolina ad reservations by about one-third, although other Republican groups have largely maintained their planned spending. The NRSC has spent $7.9 million in North Carolina and $3.6 million in Georgia through the end of August. Republican leaders, including Senate Majority Leader John Thune and NRSC Chairman Sen. Tim Scott, say the party remains committed to both states. Thune recently headlined a fundraiser for Collins with Georgia Gov. Brian Kemp that raised more than $400,000, while Trump and Vice President JD Vance recently visited North Carolina. Collins' campaign said 1 in 10 Georgia voters remain undecided about him, while Republicans are also directing more than $100 million toward Texas. Some Republicans, including Texas Sen. John Cornyn, argue resources should shift toward states where spending can have greater impact. Analysts and campaign operatives say Whatley's crime-focused message has not yet gained traction against Cooper's affordability and economic agenda, while Ossoff has warned Democrats not to become complacent.
