Thesis

CONDITIONAL CALL: this resolves only if Tucker Carlson declares as a 2028 R primary candidate with serious organization (donors, early-state infrastructure). Voids otherwise. EHIQ 35% reflects head-to-head register analysis — IF Tucker runs seriously, he retains some structural capability to challenge Vance. Per-candidate prior register scoring placed Tucker as the strongest in the 7-candidate corpus across both parties, but 2026-05-22 TIQ specificity re-scoring shows Vance 24.98 > Tucker 10.89 — contradicting the prior register-strength axis. Polymarket has no direct conditional market — its presidency sub-markets price the joint probability (Tucker runs × Tucker wins primary × Tucker wins general), not the head-to-head conditional. Separate "unconditional" probability of Tucker beating Vance overall is much lower (~5-7%) because the bridge between architecture and probability is whether he declares with serious organization.
  1. 1.Prior register reading: Tucker had the strongest primary-stage register in the prior 7-candidate corpus EHIQ scored across both parties. 2026-05-22 TIQ specificity re-scoring contradicts this on the specificity-feature axis (Vance 24.98 > Tucker 10.89).
  2. 2.Mechanism (prior thesis): register strength translates to primary debate dominance + early-state retail conversion + MAGA-base mobilization. Tucker has the architecture of a winning R primary candidate — IF he runs.
  3. 3.The constraint is structural, not capability: no campaign apparatus, no donor network, no early-state infrastructure currently. Conditional on him assembling those, EHIQ 35% reflects a register-strength advantage now partially de-rated against 2026-05-22 specificity scoring.
  4. 4.Path requires either Trump endorsement redirect or contested-Trump-endorsement scenario. With Trump backing Vance, Tucker's conditional probability is ~20-25%. With Trump-neutral or Trump-pivot, it rises to 50%+.
  5. 5.Resolution criterion: voids if Tucker does not declare with serious organization by Q1 2028.
  6. 6.Companion call (unconditional): Tucker presidency at EHIQ 2% / Polymarket 2.85% — that's the joint probability without the conditioning.
  7. 7.PROBABILITY REVISION TIMESTAMPED 2026-05-22: EHIQ 40% → 35% after SEM v1.2 build + TIQ 2026-05-22 specificity re-scoring. SEM v1.2 nomination probabilities: Vance 65.56% vs Tucker 10.84% — structurally Vance dominates. TIQ specificity (per `conviction_scoring_summary_2026-05-22.json`): Vance 24.98 (MODERATE_CONVICTION) > Tucker 10.89 (AMBIGUOUS) — directly contradicts the prior thesis claim that Tucker has the strongest register. §4 OOS Phase C FAIL (ρ=+0.18, p=0.35) prohibits claiming TIQ is method-validated, but per Eric verbatim 2026-05-22 — "TIQ is one analytical input to conviction, NOT a self-validating signal" — the specificity-feature contradiction informs the conviction call. Conservative 5pp downward acknowledges the de-rated register-strength axis while preserving the underlying conditional architecture.
