FAQ
How does it work?
The model calculates how likely a state is to vote for a candidate based on several factors:
- The average "base odds" for a state, calculated using five different forecast models (Cook, Sabato, RCP, FiveThirtyEight, and JHK Forecasts) as well as Polymarket's betting odds.
- Most recent 10 polls, including approval rating polls of the current president, favorability polls of the incumbent president, Democratic nominee, and Republican nominee, and state-by-state match-up polls.
- Historic Senate, House, and Presidential results going back to 1992, which help factor in emerging trends and partisan shifts.
- Presidential Primary turnout
The state is ran through 10,000 election simulations using the "Monte Carlo" method.
Is it accurate?
Maybe. Obviously, there's no real way to know until election day. I tested the model with the 2020 Presidential Election and came out with the following results. No data has been changed, aside from removing results data from 2022 and 2020 and replacing polls from 2024 with appropriate ones from 2020.
