Our goal

The most accurate predictive modelling and research for elections, behaviour and the Overton window.

We are a new, non-partisan US research firm. The Overton window is the range of ideas the public treats as acceptable at a given time.

Accuracy is a goal we can be checked against: we will publish every forecast before the result and score it after. How we score forecasts

Source: NBC News / TargetSmart national early-vote tracker, Oct 23, 2026; 2024 at the same point (Oct 25, 2024). Caveat: TargetSmart models party in 21 states, and party is not vote choice. Democrats have voted early in larger numbers since 2020. Why that matters
