Georgia Republican Senate nominee?

Brian Kemp has withdrawn from consideration for the 2026 Senate election. Brian Kemp, who was previously considered a potential candidate for the 2026 Georgia Republican Senate nomination, has publicly announced his decision not to run for the U.S. Senate in 2026 ^{[^]}. This means Kemp will not challenge Democratic Senator Jon Ossoff, and he is consequently not in a position to secure any public endorsements for this specific race ^{[^]}.

Marjorie Taylor-Greene has not yet secured the specified endorsements. Marjorie Taylor-Greene is listed as another potential candidate for the 2026 Georgia Republican Senate nomination ^{[^]}. However, the available research does not contain any specific information indicating that she has secured public endorsements from Donald Trump Jr., Kari Lake, Steve Bannon, Charlie Kirk (Turning Point Action), or Matt Gaetz for her potential 2026 Senate campaign ^{[^]}.

A determination of the first candidate cannot be made. Based on these findings, it cannot be determined which of the two potential candidates is first to secure at least three of the specified public endorsements. One individual has publicly withdrawn from contention, and no such endorsements are reported for the other within the provided sources.

The initial two FEC filings for 2025 candidates in the Georgia Republican Senate primary are not yet available; however, an analysis of the first two quarters of 2024 (Q1 and Q2) provides insight into candidate fundraising. Mike Collins reported combined total receipts of $417,008.00, with 99.51% of his funds coming from large-dollar donors and only 0.49% from small-dollar donors, and no PAC contributions recorded in these filings ^{[^]}. During the same period, Buddy Carter raised a combined total of $629,050.00, with 99.39% derived from a combination of large-dollar individual donors and PACs, and approximately 0.61% from small-dollar donors ^{[^]}.

Fundraising patterns suggest an establishment-leaning support base, not grassroots movements. The "Dooley for Georgia" committee, in contrast, reported total receipts of $25,000.00, which were entirely sourced from candidate loans, showing no contributions from small-dollar donors, large-dollar donors, or PACs ^{[^]}. The strong reliance of both Mike Collins and Buddy Carter on large-dollar donors, coupled with significant PAC support for Carter, indicates an establishment-leaning support base. The negligible percentages of funds from small-dollar donors suggest a lack of broad grassroots appeal, while "Dooley for Georgia" also demonstrated no broad donor base with its exclusive reliance on candidate loans ^{[^]}.

Specific data on county-level endorsements for Georgia Republican candidates is currently unavailable. The available web research does not contain the necessary information to determine which potential candidate will have secured the majority of public endorsements from Georgia's Republican county-level party chairs by the end of Q2 2025.

Related information from specific groups does not fulfill the query's criteria. While Josh McKoon was re-elected as the state GOP chairman on June 9, 2025 ^{[^]}, this pertains to state party leadership rather than county-level candidate endorsements. Similarly, the Georgia Republican Assembly (GRA) has issued various endorsements in 2025, including a 7th & 11th Regional Endorsement Convention on April 24, 2025, and local RA endorsements around April 29, 2025 ^{[^]}. However, these endorsements originate from a specific organization (GRA) and are not explicitly from county-level party chairs.

Prediction markets offer speculative insights, not direct endorsement tracking. Several sources detail prediction market odds for the Georgia Republican Senate nominee in 2026, providing speculative insights into potential winners ^{[^]}. For instance, Polymarket lists predictions for the Georgia Republican Senate Primary winner ^{[^]}, and Kalshi provides odds for the 2026 Georgia Republican Senate nominee ^{[^]}. These markets reflect perceived candidate strength but do not track actual endorsements from county-level party chairs, which was the specific metric requested ^{[^]}. Therefore, identifying the candidate who will have secured the majority of such endorsements by the specified deadline is not possible with the current research.

Specific polling data for the Georgia GOP Senate primary remains unavailable. The research did not identify any candidate consistently showing the highest favorability rating among 'moderate' or 'independent' voters in statewide Georgia GOP primary polling conducted in the first half of 2025 for the Senate race. The detailed polling information requested for this specific timeframe and voter segment was not contained in the provided web research. Therefore, no direct evidence was found to identify a candidate meeting the specified criteria for the Georgia GOP Senate primary during the first half of 2025.

Sources reviewed fell outside the requested criteria or scope. Several sources found were dated outside the specified first half of 2025, such as an AJC poll ^{[^]} and another AJC article ^{[^]} from October and November 2025. Other resources, including PredictIt ^{[^]} and Polymarket ^{[^]}, were prediction markets that provide odds rather than direct public opinion polling data on voter favorability. Additionally, some linked information pertained to different elections, including the 2024 Presidential primary ^{[^]}, the 2022 Gubernatorial election ^{[^]}, or the 2026 Gubernatorial primary ^{[^]}. One article discussing a potential general election matchup between Governor Kemp and Senator Ossoff ^{[^]} also did not focus on GOP primary favorability among specific moderate or independent voter segments.

Georgia Governor Brian Kemp decided against a 2026 U.S. Senate campaign. He has publicly confirmed his decision not to form a federal exploratory committee or file a statement of candidacy for the U.S. Senate in 2026. This choice, widely reported by various news outlets in early May 2025, with specific articles on May 5, 2025, detailed his intent not to run ^{[^]}. This announcement definitively precedes any actions related to an exploratory committee or candidacy filing, which would have been due by the January 31, 2026, deadline.

Kemp's choice significantly alters the 2026 Republican Senate field. Prior to his definitive announcement, Governor Kemp had maintained suspense within the Republican Party regarding his future political ambitions, particularly concerning a potential Senate bid ^{[^]}. However, reliable reports from sources including the Georgia Recorder, The Atlanta Journal-Constitution, and WABE have confirmed that Kemp will not challenge the incumbent Senator Jon Ossoff ^{[^]}. His decision is considered a significant development for Georgia's 2026 Senate race, as it "scrambles the projected field" and is expected to trigger a competitive scramble among other Republicans for the nomination ^{[^]}. Consequently, Governor Kemp will not be pursuing any steps toward a U.S. Senate campaign by the established January 31, 2026, deadline.
