French Second-Round Transfer Logic

Overview

This pillar analyzes the 'Republican Front' dynamic in France's two-round voting system. It predicts how voters from eliminated first-round candidates reallocate their support, which is crucial for determining the final winner.

What It Does

The model examines historical vote transfer matrices from past elections to establish baseline probabilities. It then adjusts these probabilities based on current factors, such as public endorsements from losing candidates and the ideological distance between the remaining contenders and the eliminated ones.

Why It Matters

Second-round elections are not won on core support alone; they are won by attracting voters from defeated opponents. This pillar provides a crucial edge by quantifying the strategic 'blockage vote' that often decides the outcome against more polarizing candidates.

How It Works

First, the pillar ingests first-round polling data or results to identify the two finalists and all eliminated candidates. Second, it references a database of historical transfer patterns for similar ideological matchups. Finally, it weights these patterns with the impact of current endorsements to project a final vote share for each candidate.

Methodology

The core calculation is: Projected R2 Vote = Base R1 Support + Σ (Eliminated Candidate_i Vote Share * Transfer Rate_i). The 'Transfer Rate' is derived from historical post-electoral surveys from sources like Ipsos, adjusted for the strength and clarity of endorsements from eliminated candidates' parties.

Edge & Advantage

This provides an edge by moving beyond simple popularity metrics to model the anti-candidate 'blockage vote', a decisive factor that many generic election models overlook.
