Estimate the probability of each contributing factor (Le Pen's eligibility, whether a designation has occurred, and Bardella's designation) and blend them via weighted average to distribute probability mass across the multiple-choice candidate options, with Le Pen favored if eligible and Bardella favored otherwise.

## Question
Who will be publicly designated as the National Rally candidate for the 2027 French presidential election on September 1, 2026?
## Description / Resolution Criteria
## Description
BFM TV: [2027 Presidential Election: Marine Le Pen assures that she will "campaign" for Jordan Bardella in the event of a legal impediment](https://www.bfmtv.com/politique/front-national/presidentielle-2027-marine-le-pen-assure-qu-elle-fera-la-campagne-de-jordan-bardella-en-cas-d-empechement-judiciaire_AN-202605220255.html)
`{"format": "bot_tournament_question", "info": {"hash_id": "8176d8e95e5126c2", "sheet_id": "58"}}`
## Resolution Criteria
This question resolves to the person who has been publicly designated as the National Rally/Rassemblement National candidate for the 2027 French presidential election as of September 1, 2026.
## Options
- Marine Le Pen
- Jordan Bardella
- Someone else or nobody before September 1, 2026
## Sub-question decomposition (planner)
- (w=0.40) Will Marine Le Pen be legally eligible (no disqualifying ineligibility in effect) to run as the National Rally candidate as of September 1, 2026? — Le Pen's appeal of her ineligibility ruling is the central variable determining whether she or a substitute is designate
- (w=0.25) Will the National Rally have formally/publicly designated any candidate (rather than leaving it undecided) by September 1, 2026? — The question resolves to whoever is designated; if no one is publicly designated yet, that affects which option resolves
- (w=0.35) Will Jordan Bardella be the publicly designated National Rally candidate as of September 1, 2026? — Bardella is the explicit backup named by Le Pen in case of legal impediment and the most likely alternative designee.
## Synthesized evidence
1. [sq1 | claude_news | MODERATE cred 70 | DOWN | DATED] BFM TV reports Marine Le Pen said she would campaign for Bardella in the event of a 'legal impediment' to her candidacy.
2. [sq1 | wikipedia_lookup | STRONG cred 90 | NEUTRAL | DATED] The 2027 French presidential election is scheduled for April 2027; Le Pen ran in 2012, 2017 and 2022.
3. [sq1 | wikipedia_lookup | WEAK cred 55 | NEUTRAL | DATED] Le Pen remains a sitting National Assembly member and RN parliamentary leader, with no Wikipedia note of a currently disqualifying ineligibility.
4. [sq3 | claude_news | MODERATE cred 70 | DOWN | DATED] Le Pen framed Bardella as her backup candidate should she face a legal impediment, implying she remains the first-choice candidate otherwise.
5. [sq3 | wikipedia_lookup | MODERATE cred 80 | NEUTRAL | DATED] Bardella has been RN party president since 2022, positioning him as the natural alternative candidate.
6. [sq2 | article_search | WEAK cred 30 | NEUTRAL | RECENT] No relevant reporting found confirming a formal/public RN candidate designation by September 1, 2026.

### Polymarket
- "Will Roberto Sánchez Palomino win the 2026 Peruvian presidential election?" → Yes: 0.00, Volume: $35.9M
- "Will Donald Trump publicly insult someone on June 21, 2026?" → Yes: 0.00, Volume: $727.2K
- "Will Thomas Massie win the 2028 US Presidential Election?" → Yes: 0.01, Volume: $7.4M
Information gaps:
- Status/outcome of Le Pen's ineligibility appeal as of mid-2026
- Whether RN has set a formal timeline for designating its 2027 candidate
- Base rate: how early French parties historically name presidential candidates
- Any 2026 polling on Le Pen vs Bardella as RN standard-bearer
Key uncertainties:
- Whether Le Pen's legal ineligibility is in effect or suspended by Sept 1, 2026
- Whether RN designates a candidate this early or stays undecided
- If Le Pen ineligible, whether Bardella is formally named by Sept 1
- Outcome and timing of any appeals court ruling
## Required pre-forecast walkthrough
Before giving probabilities, address these explicitly in your rationale:
(a) The time left until the question resolves.
(b) The status quo outcome — the option most likely if nothing changes from today.
(c) An outcome that would be SURPRISING but plausible.
## Calibration guidance
- **Status quo anchoring.** Good forecasters put extra weight on the status quo option because the world changes slowly most of the time.
- **Leave moderate probability on most options.** Good forecasters don't drop options to ~0% — leave ≥3-5% on every option to account for unexpected outcomes, unless you have strong specific evidence ruling them out.
- Avoid uniform-distribution laziness — most options are not equally likely.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) for these options appear in the evidence, treat them as a strong prior and stay close to them absent specific contrary evidence.

"rationale": "(a) There are roughly 3 months from the May 2026 evidence date to the September 1, 2026 resolution, and ~7-8 months from the question\u0027s framing. (b) Status quo: Le Pen remains RN\u0027s presumptive standard-bearer (her three prior candidacies, sitting MP, party loyalty), but French parties typically formally designate presidential candidates relatively late (often within the year before the election), so a \u0027no formal designation yet\u0027 outcome is very plausible by Sept 2026. (c) Surprising-but-plausible: Le Pen\u0027s appeal upholds her ineligibility and RN formally pivots to Bardella before September 2026. The decisive variable is Le Pen\u0027s appeal of her ineligibility, with a verdict expected around summer 2026; if eligibility is restored she is the natural designee, if upheld Bardella is the explicit backup. Given that formal early designation is uncertain and the appeal outcome is unresolved, I place the most weight on \u0027someone else or nobody\u0027 (i.e., no formal designation yet), substantial weight on Le Pen as presumptive candidate, and meaningful weight on Bardella as the named contingency.",
