Head-to-Head State Polling Aggregate

Overview

This pillar analyzes head-to-head polling data from the most decisive swing states. It provides a weighted average that cuts through national noise to signal who is leading where it matters most.

What It Does

It aggregates high-quality polls from the seven core presidential battleground states: AZ, GA, MI, NV, NC, PA, and WI. Each poll is weighted based on the pollster's historical accuracy, sample size, and recency. The pillar then calculates a composite margin, offering a precise view of the race.

Why It Matters

Presidential elections are won in the electoral college, not by the national popular vote. This pillar focuses exclusively on the states that will likely decide the outcome, providing a more actionable and predictive signal than broad national polls.

How It Works

First, the system continuously ingests new head-to-head polls from A and B rated pollsters for the target swing states. It then applies a time-decay formula, giving more weight to recent polls. Finally, it combines these weighted polls to produce a single, reliable aggregate margin for each state and a composite average.

Methodology

The pillar calculates a time-decay weighted average. Polls are weighted using the formula: Weight = (Recency * 0.5) + (Pollster Grade * 0.3) + (Sample Size * 0.2). Recency uses a 14-day half-life. The final output is the weighted average margin between the two leading candidates.

Edge & Advantage

It ignores low-quality polls and national trends, focusing only on high-grade, state-level data that directly correlates with electoral college outcomes.
