Candidate Net Favorability (Swing States)

Overview

This pillar isolates personal popularity metrics within the seven decisive US swing states. It separates policy alignment from personality to determine the emotional ceiling and floor of a candidate's support.

What It Does

We aggregate polling crosstabs from Pennsylvania, Michigan, Wisconsin, Arizona, Georgia, Nevada, and North Carolina. The system specifically extracts 'Favorable' versus 'Unfavorable' ratings rather than head-to-head vote choice. It adjusts for partisan leans of specific pollsters and filters for likely voter screens over registered voter screens.

Why It Matters

In close elections, a candidate's net likability is often a leading indicator for how undecided voters will eventually break. High 'strongly unfavorable' ratings create a hard ceiling on vote share that is difficult to overcome with policy proposals alone.

How It Works

The analysis ingests data from state-level polls and calculates a 'Net Favorability' score (Favorable minus Unfavorable). It applies a time-decay weight to prioritize recent shifts in sentiment. Finally, it compares these state-level net scores against historical winning benchmarks for those specific demographics.

Methodology

Net Score = (% Favorable - % Unfavorable). We utilize a 14-day exponential moving average (EMA) of state-specific polls. Data is weighted by pollster rating (historical accuracy) and sample size. We specifically track the 'Intensity Gap' defined as (% Strongly Favorable - % Strongly Unfavorable).

Edge & Advantage

Head-to-head polls are often noisy due to third-party candidates and undecideds. Net favorability provides a cleaner signal of a candidate's potential vote cap and floor.
