Down-Ballot Drag & Scandal Contagion

Overview

This pillar analyzes how a major scandal involving a top-of-the-ticket candidate impacts the electoral chances of down-ballot candidates from the same party. It quantifies the 'contagion effect' to find hidden risks and opportunities in local races.

What It Does

It monitors national media for major political scandals and tracks their sentiment and volume. The model then correlates this data with shifts in local news coverage and polling for related down-ballot races. It specifically looks for signs of 'distancing' by local candidates as a key indicator of perceived electoral damage.

Why It Matters

National events create ripples that are often missed by hyper-focused local race analysis. This pillar provides an edge by identifying which down-ballot races are most vulnerable to top-down negative pressure, often before local polls fully reflect the change.

How It Works

First, a high-impact scandal is identified using news volume and sentiment analysis. Second, the system tracks media mentions of the scandal alongside local candidates in key districts. Third, it analyzes generic ballot polling and specific race data for negative correlations. Finally, it synthesizes these signals into a contagion score for affected races.

Methodology

The model uses NLP to perform sentiment analysis on news articles from national and local sources, focusing on a 14-day window following a scandal's peak. It calculates a 'Distancing Score' based on the frequency of public statements where local candidates diverge from the party leader. This is correlated with generic ballot polling shifts using a time-series regression model to estimate the polling impact.

Edge & Advantage

This pillar predicts outcomes in local races that the market misprices because it is too focused on national trends or candidate-specific factors.
