A Predictive Model of U.S. Presidential Elections
The Core Insight
It's not about who gets attacked.
It's about whether attacks seem legitimate — and how targets respond.

Illegitimate attacks create humanization opportunities. The candidate who seizes those opportunities through effective response wins. Attack legitimacy matters more than attack intensity.
Beshear vs. Vance
Andy Beshear has won twice in a Trump +26 state — proven crossover appeal. JD Vance carries the institutional burden of the incumbent party and the "heir problem" that historically disadvantages successors.
The key variable is Democratic attack strategy. If they repeat the persecution-trap mistakes of 2024, they activate humanization opportunities for Vance. If they focus on policy and let Vance's own words work against him, they avoid the trap.
Current Projection: BESHEAR
Conditional on Democrats avoiding the persecution trap
Science, Not Magic
This model is built on the premise that human behavior operates within bounded, predictable ranges. However, behavior can change. Candidates can shift strategy. Scandals can erupt. External shocks — war, recession, pandemic — can redraw the landscape entirely. Predictions assume current trajectory holds. If circumstances change materially, predictions will be updated. Testable. Falsifiable. That's how science works.
"It's NOT the economy, stupid."
Economy matters — but it works through the legitimacy variable, not around it. A bad economy makes attacks on the incumbent party seem more legitimate. A good economy makes attacks seem unfair. When other factors create larger legitimacy effects, economy becomes secondary noise.
