METHODOLOGY

This model is made up of two components, two which everyone that's a politics junkie knows well - the fundamentals and the polls.

The model fundamentals are made up of three components in of themselves - a presidential composite using

  • 5% 2012 presidential election results
  • 15% 2016 presidential election results
  • and 80% 2020 presidential election results.
On top of that, the presidential composite is adjusted for district trends over the last 2 years, which altogether makes a partisan lean index. But there are 3 states where there's been top-two primary results from 2022 that can suitably replace a partisan lean index - Alaska, California, and Washington, so AK/CA/WA adjusted (for primary-general swing) primary results MOSTLY replace the partisan lean index in those states. However, a partisan lean index is on its own not a good way to forecast elections, so that's why I've also used; As for the polls, it's a little more simple; polling data simply uses a weighted average of every poll based off of recency. Poll margins are also edited based off if they're a Democratic or Republican internal polls, since internal polls are usually 5 points more biased toward the surveying party.
After the fundamentals and poll margins are calculated, they're weighted together using the amount of polls that have been produced, which produces an exact margin. Once an exact margin is created, a randomizer of +2 to -2 points is ran 250,000 times, and the median margin is used as the neutral year forecast margin. The neutral year forecast margin is then added to the state level environment (which is calculated from the national environment), which produces the official acctuallydavid.com forecast margin for the state.
