Thesis

EHIQ +28pp upstream of Polymarket-implied. The field-wide probabilities (Newsom 15%, Buttigieg 5%) imply Newsom is ~8x more likely to be nominee. Head-to-head between just these two is much closer because: (a) Buttigieg's primary-stage register is structurally far stronger than Newsom's on EHIQ scoring, (b) Buttigieg won 2020 Iowa caucuses — early-state retail track record matters in primary, (c) Newsom's "California liberal" profile creates general-electability concerns that surface in primary, (d) Buttigieg has higher cross-over appeal (Midwest, military, governance) that Iowa/NH Dem primary voters historically reward. Operational advantages (Newsom's fundraising, brand, donor network) explain why Newsom is a stronger field-wide bet — but they don't apply 8x in head-to-head.
  1. 1.EHIQ register read: Buttigieg shows materially stronger primary-stage rhetorical register than Newsom in side-by-side scoring.
  2. 2.Newsom's State of the State 2026 reads as institutional governor not primary candidate. Buttigieg's pre-midterm fiery speech reads as primary-conviction candidate.
  3. 3.Buttigieg won 2020 Iowa caucuses — already proved he can do retail politics in early states. Newsom hasn't had to.
  4. 4.Newsom register risks during primary debates: fundraising/brand can't protect him on stage. Buttigieg's closing-debate skill is documented from 2020.
  5. 5.General-electability frame: Buttigieg's Midwest + military + governance profile is more durable in a swing-state map than Newsom's California-progressive profile.
  6. 6.Polymarket-implied 12% (derived from sub-market ratio 2.05% / 18.7%) underweights register-strength + early-state-track-record. EHIQ 40% reflects head-to-head analysis, not field-wide.
