Who will run for neocons in 2028?

GPT-5.4 (changed mind)

Vote: Rubio

I’m changing my vote to C. My earlier argument overweighted who is most likely to lead the GOP in 2028 rather than who would run specifically for the neocon lane. On that narrower reading, Vance is a poor fit. He is strongly identified with the populist-nationalist, post-neocon wing of the party and has explicitly taken positions against hallmark neocon foreign-policy preferences. Trump remains effectively off the table because of the 22nd Amendment, so A is not a serious answer. That leaves Rubio. Multiple models made the same core point persuasively: Rubio is the only option here with a durable record of hawkish, interventionist, establishment-aligned foreign policy views. If someone is going to carry the neocon banner in 2028 among these three, Rubio is the natural choice. The most convincing formulation came from Claude Opus 4.6, which clearly separated 'likely overall GOP successor' from 'neocon standard-bearer.' That distinction is what changed my mind.

Grok 4.1 Fast

Vote: Rubio

Sticking with C: Rubio. No arguments changed my mind; the consensus on C reinforces it, while GPT-5.4's B vote misreads the question. The query specifies 'run for neocons'—neoconservatives as a distinct faction seeking their ideological champion, not the GOP frontrunner. Rubio alone embodies neocon hallmarks: interventionism, hawkishness on China/Iran, Israel support, and global leadership—directly opposing Vance's 'America First' isolationism and Ukraine skepticism. Trump is term-limited (22nd Amendment) and, at 82, irrelevant. Vance inherits MAGA populism, which neocons decry as betraying Reaganism; he'd alienate their donor base. GPT-5.4 conflates neocon weakness in the broader GOP with no neocon runner—neocons will rally behind Rubio's infrastructure and purity, as Claude, Gemini, et al. detail. In a crowded 2028 primary, factions field their own; Rubio is theirs.

Gemini 3.1 Pro

Vote: Rubio

I am maintaining my vote for Rubio. The prompt specifically asks who will run 'for neocons' in 2028, which means identifying the candidate most aligned with that specific ideological faction, not simply who is most likely to win the overall nomination. GPT-5.4 argues for Vance based on his general viability and path to the nomination. However, Vance is explicitly associated with the non-interventionist, America First wing of the party and has actively criticized neoconservative foreign policy, making him highly unlikely to be the standard-bearer 'for' the neocons. Marco Rubio is the only option listed who possesses a long-standing track record of hawkish, interventionist foreign policy that aligns with traditional neoconservatism. Therefore, he is the only logical choice to represent that specific political lane.

Claude Opus 4.6

Vote: Rubio

I'm maintaining my vote for Rubio. The deliberation has only reinforced my position, with four out of five models (including myself) converging on C. The one dissenting vote from GPT-5.4 for Vance acknowledged that Rubio is 'more traditionally hawkish and more clearly associated with neoconservative foreign policy,' but argued Vance would inherit establishment support as part of a broader coalition. This conflates the question of who will run as the Republican frontrunner with who will run *for neocons* specifically. The question asks about the neoconservative lane, not the overall GOP nomination. Vance is the antithesis of neoconservatism. He has opposed Ukraine aid, questioned NATO commitments, and explicitly rejected the interventionist worldview. Neocons would not rally behind him — they would seek an alternative, and Rubio is that alternative. Rubio's hawkish record on China, Iran, Venezuela, Cuba, and his strong pro-Israel stance make him the natural home for neoconservative voters and donors looking for representation in the 2028 field. Even serving as Trump's Secretary of State doesn't change his ideological DNA — if anything, it gives him foreign policy credentials that strengthen his case. The near-unanimous consensus here reflects sound reasoning: Trump can't run, Vance won't carry the neocon banner, and Rubio is the clear answer to this specific question.

DeepSeek V3.2

Vote: Rubio

Trump is effectively disqualified from a 2028 run due to the 22nd Amendment, assuming he serves a second term. Moreover, his 'America First' platform fundamentally conflicts with neoconservative interventionism and global engagement. JD Vance, while a likely contender for the GOP nomination, embodies the populist-nationalist movement that has marginalized neocons within the party. His foreign policy views are isolationist, making him an implausible standard-bearer for neoconservatives. Marco Rubio remains the only candidate with deep ideological ties to neoconservative principles, including robust foreign policy activism and democracy promotion. As neocons seek relevance in a shifting GOP, Rubio offers their most viable path to influence in 2028.

Kimi K2.5

Vote: Rubio

The consensus remains clear: Marco Rubio is the only figure among these three who actually represents neoconservative ideology. Vance—the overwhelming favorite for the 2028 GOP nomination—explicitly embodies the nationalist-populist wing that has actively displaced neoconservatism from the party. He opposes the interventionist foreign policy, global alliance structures, and democratic promotion that define the neocon movement. Rubio, conversely, maintains the donor networks, policy infrastructure, and ideological track record that align with interventionist foreign policy. While Vance will likely run in 2028, he will not run 'for neocons'—he will run against their remaining influence within the GOP. Trump is constitutionally barred and represents the same anti-neocon populism. Therefore, if neoconservatives seek a standard-bearer in 2028, Rubio is their only viable option from this list.

Final Summary

The AI Roundtable reached a unanimous consensus that Marco Rubio is the only logical choice for neoconservatives, but only after GPT-5.4 abandoned its initial support for JD Vance. While most models immediately identified Rubio as the ideological standard-bearer for hawkish foreign policy, GPT-5.4 originally argued that Vance would inherit the establishment coalition until Claude Opus 4.6 persuasively separated the concept of a 'GOP frontrunner' from a 'neocon champion.'

All 6 models agreed on "Rubio" after discussion

Strongest Arguments

• Vance: Vance enters 2028 with national visibility and a natural claim to inherit the party coalition, potentially folding establishment support into a broader nationalist-populist front.
• Rubio: Rubio is the only candidate with a consistent record of hawkishness on China, Iran, and global intervention, making him the natural ideological home for neocon donors and voters seeking a standard-bearer.

Key Turning Points

• GPT-5.4 flipped its vote from Vance to Rubio after acknowledging Claude Opus 4.6's distinction between a general party successor and a specific factional representative.
