Biden/Trump TIE
This summary assumes that any state with a current poll average margin of less than 5% could go either way, leading to the two best cases where one candidate wins all of these states. The "Expected" case is when each candidate wins every state they currently lead, regardless of how small that lead may be.
This model assumes poll errors in states are independent of each other. State win probabilities are derived from analyzing how Election Graphs poll averages at similar times before the election have historically deviated from actual election results from 2008 to 2020. This model accounts for how things can change in the time remaining.

Accounting For Time Left Before Election
Median:

1σ (68.27%) range:
Trump by 36 ----- Trump by 184
2σ (95.45%) range:
Biden by 160 ---------- Trump by 228
3σ (99.73%) range:
Biden by 326 --------------- Trump by 346
Odds:
Biden: 8.7% — Tie: 0.0% — Trump: 91.3%
This model assumes poll errors in states will be identical nationwide. State win probabilities are derived from analyzing how Election Graphs poll averages at similar times before the election have historically deviated from actual election results from 2008 to 2020. This model accounts for how things can change in the time remaining.

The poll average generally uses the last 5 polls (by middate).
If there is tie for the middate of the oldest poll to be included, all polls with that middate are included.
If the result is exactly on the border between categories (0%, 5% or 10% margin) older polls are pulled in one by one until the result is clearly within a category.
When there are not enough actual polls for the poll average, results from prior presidential elections are used to fill in the average.
If a pollster releases multiple results based on the same sample they are weighted so collectively they count as "1 poll".
On state detail pages this is noted by an [N], shading in the listing, and a different color data point in the graph.
State win probabilities are calculated based on 2008-2020 data using the methodology in the January 2023 blog post titled "Prepping the Math Stuff for 2024".
