Ranks all 2028 Democratic candidates by composite Ferguson Viability Score (0–100), anchored on the empirical model in Ferguson, Jorgensen & Chen (2018, INET Working Paper, REFERENCES.md §Bibliography) and on the 1992–2024 Democratic-contested-primary calibration described in the methodology card below. Score above 40 = historically viable; below 40 = long shot at this stage. Trend arrows reflect 30-day momentum based on public signals. ANALYST
← Viability threshold: candidates below 40.0 historically have <5% nomination rate (ANALYST — Catalyst internal calibration) | Trump 2016 anomaly: 14.0 score, won via large earned-media coverage (Sides-Tesler-Vavreck 2018 "Identity Crisis" est. ~$2-5B equivalent free media; SOURCED).
📊 Methodology — Ferguson Viability Scoreboard ANALYSTas of …
The Ferguson Viability Score (0–100) is the Catalyst composite of (a) Q4-fundraising-share position relative to field, (b) signal-donor commitments, and (c) bundler-network coverage. It is calibrated against the 1992–2024 Democratic contested-primary cycles using a method anchored on Ferguson-Jorgensen-Chen (2018) but extended with the 4-cycle InfluenceRanker back-test (backend/data/backtest/ranker_backtest_2016-2022.json, AUC composite 0.73 vs. dollar baseline 0.60). The composite-vs-nomination R² ≈ 0.71 claim is an internal calibration; the reproducible notebook is a Phase 8 DEV_PLAN deliverable. Until that ships, the composite is labeled ANALYST. The viability threshold (40.0) and the 92% historical-accuracy claim are likewise internal calibrations. Component scores below 40 historically correspond to <5% nomination probability in this cohort — but the underlying cohort is small (≈9 D contested cycles) so the threshold should be read as a heuristic, not a frequency estimate.

ⓘ
Maps the invisible primary calendar from now through Iowa 2028. The shaded 'threshold window' (Sep–Dec 2026) is when signal donors must commit to produce viable Q4-1 fundraising position — the single strongest predictor in Ferguson's model. Historical reference lines show when past nominees crossed each milestone. The candidate trajectory bars (Harris / Buttigieg / Newsom → Q4 2027 share projection) are ANALYST projections from the Ferguson model, not measured fundraising data — see the Methodology card below. Phase 9.2 audit (2026-05-18) added the ANALYST label — prior section was unlabeled.
First-mover donors with cascade effects from the real actor database
loading...
ⓘ
Tracks the ~20 donors and bundlers whose first-mover commitments have historically triggered cascade effects in prior primaries (see Biden 2020: Clyburn → 72-hour nomination sequence). 'Commit probability' is editorial assessment; 'Cascade effect' shows which actors a commitment would activate next. Watch the 'days to optimal window' column — timing matters as much as the commit itself.
🎯 Methodology — Signal Donor Tracker ANALYSTas of …
Influence weights are an editorial composite (0–1 scale) of (a) past-cycle network centrality from the Catalyst 68-actor influence graph (docs/CAUSAL_GRAPH.json), (b) replaceability from EFFECT_SIZES.md Table 0 (Battaglini et al. 2024, NBER WP 32649), (c) cascade-coverage of downstream donors. Commit probability and optimal window are strategist judgement, not measured signal. Cascade effect lists downstream activations anchored on historical precedent (Obama 2007 Hollywood fundraiser, Biden 2020 SC-Clyburn cascade) per Cohen-Karol-Noel-Zaller (2008).

🚨 FIRST MOVER ALERT
No signal donor has publicly committed yet. The next signal donor to commit will trigger a cascade affecting 12-15 network actors within ~47 days. Historical evidence (Obama 2008): Geffen's February 2007 Hollywood fundraiser → +$12M Q2, bundler cascade in 45 days → nomination trajectory locked. Estimated nomination probability impact for recipient: +8-18 points.

📈 Ferguson Model Calibration
Q4 fundraising share vs nomination probability | R²=0.71 | 1992-2024
ⓘ
Historical scatter of Q4 year-before fundraising position vs. actual nomination outcome across cycles 1992–2024. The composite R² ≈ 0.71 is an internal Catalyst calibration (ANALYST — reproducible notebook pending Phase 8). Current 2028 candidates are plotted as projections. The Trump 2016 anomaly shows that large free-media coverage (Sides-Tesler-Vavreck 2018 estimate ~$2–5B equivalent) is the only documented substitute for donor capital.
📈 Methodology — Calibration Scatter SOURCED (historical) + ANALYST (2028 projections) as of …
Historical Q4-share / nomination-outcome points are sourced from OpenSecrets cycle-summary pages, Cohen-Karol-Noel-Zaller (2008) The Party Decides, and the Mayer-edited The Making of the Presidential Candidates volumes (1996/2001/2008/2012). 2028 projections (Harris, Buttigieg, Newsom triangles) are ANALYST — Catalyst projection model based on current Q1 2026 FEC filings + Ferguson-composite weights. The regression line and 50% CI band are computed on the sourced points only; projections are not used in the fit.

Quick-reference action table distilling each candidate's single highest-leverage intervention based on the causal graph. Use this to prioritize outreach sequencing — the probability impact estimates are based on historical effect sizes from Grade-A causal evidence (event studies, diff-in-diff). Window = optimal timing for maximum cascade effect.
⚡ Methodology — Intervention Priorities ANALYST (impacts anchored on Grade-A effect sizes) as of …
Each priority is an editorial selection of the single highest-leverage 6–12-month action for the candidate, written by Catalyst analysts. The +X–Ypts probability impact ranges are anchored on rows of EFFECT_SIZES.md: e.g. Clyburn-style endorsement uses the Biden-2020 +35–40pt SC-Black-voter cascade (Grade A event study); first-signal-donor commit uses the Obama-2008 Hollywood cascade (+8–12pt Q1 fundraising jump, Cohen-Karol-Noel-Zaller 2008, Grade A). These are analogues, not forecasts for 2028 — the actual cycle impact depends on factors we cannot measure ex-ante.

Key insight: All 6 VIABLE/WATCHING candidates have their #1 action concentrated in Q3 2026 — the assessment phase window before the fundraising threshold period (Sep-Dec 2026). The candidate who moves first in their respective network creates cascade advantages that are difficult for later movers to overcome.

🔍 Dark Money Influence on Candidate Viability
How undisclosed spending shapes the invisible primary — estimated dark money support by candidate
Dark Money Overlay: CDO tracks ~$1.9B in undisclosed 2024-cycle political spending flowing through 501(c)(4) organizations, 527s, and shell PACs (OpenSecrets 2024 cycle summary). While dark money doesn't directly determine Ferguson scores, it shapes the media environment, voter contact operations, and elite signaling that candidates need. The 2.3× invisible-primary advantage figure is ANALYST — Catalyst internal estimate from 2024-cycle infrastructure mapping, not a measured effect size. → Full Dark Money Tracker
🔍 Methodology — c4/Dark-Money Support per 2028 Candidate ANALYSTas of …
The per-candidate dollar values below are speculative. The named 2028 candidates have not filed candidate committees, so there is no 2025–2026-cycle c4/527 dollar flow specifically attributable to them. The values are Catalyst analyst estimates of which c4/527 infrastructure is likely to align based on (a) 2024-cycle filings of the listed vehicles, (b) post-2024 strategic positioning of the named operators, (c) historical donor-network overlap. These are not measured flows. They are alignment forecasts. Per-candidate cycle-2028 dollar totals will not exist until candidates file in 2027 — that is the gap, named honestly.

🕸 Campaign Manager Network
The hidden power brokers — a small number of elite operatives direct billions in spending across dozens of races
Network Intelligence: CDO tracks the campaign managers, senior strategists, and chief consultants who run America's most competitive races. The operative-to-funds-directed dollar totals shown below are NOT publicly verifiable at this level of attribution. Public sources (FEC SI-2 filings, OpenSecrets PAC pages) name treasurers and consultants but do not aggregate spending by individual operative. The 16-row table below should be read as ANALYST — operative names and firm affiliations are SOURCED; the dollar totals and W-L records are editorial estimates pending an AdImpact / Path-to-Win subscription we don't currently hold.
🕸 Methodology — Campaign Manager Network SOURCED (names) + ANALYST (dollar totals) as of …
Operative names + firm affiliations are SOURCED from FEC SI-2 (Statement of Independence) filings, campaign press releases, and post-election retrospectives. Funds-directed totals are not available from public sources — they would require AdImpact / Path-to-Win subscriber data the project does not currently hold; the totals shown are Catalyst analyst estimates from 2024-cycle FEC aggregate + cited press totals, with substantial uncertainty. The honest gap: until we ingest a verified SI-2 / AdImpact pipeline (DEV_PLAN Phase 8.2 — "FEC SI-2 ingestion pipeline"), the per-operative dollar columns should be treated as ranges, not point estimates.
