Current Forecast
| Biden | Trump |
|---|---|
| 349 (nc) | 187 (nc) |
This is our latest Forecast. From now until Polling Day we will publish each day what we think the result will be from voting on Tuesday.
With one days to go we forecast a decisive win for Biden with a Trump win a very slim chance. A large amount of polling released in the past 24 hours has changed a few of the races (some dramatically), but overall Trump is still well behind. Our distribution of potential results is much wider than yesterday, showing that more States are now in contention for both candidates.
Key changes since yesterday
Georgia is now too close to call
Biden back in control in Maine 2
Trump surge in North Carolina and Ohio. The latter is now his to lose.
Biden challenging in Texas
We expect a few more polls to be released over the next 24 hours and we will produce our final forecast tomorrow, together with a guide to where we think each State will end up.

Probability of Biden Winning State
Presidential Election Forecast Philosophy
Our US Presidential Election forecast is based on polling in individual states. We run a monte-carlo simulation across the entire country and then calculate the probability of each candidate winning each state or electoral district (in the case of Maine and Nebraska). From this we allocate Electoral College votes State by State giving a final total for each candidate.
Do you allocate whole States / Districts to Candidates?
As we approach Election Day, our Nowcast now moves to a full Monte Carlo simulation of the whole country. From this Nowcast onwards our seat forecast is based on allocating the total EC votes for each State / District to the candidate who “wins” in the simulation. From this we produce a probability distribution of likely outcomes.
What do you mean by Strong / Safe / Soft?
We allocate a State a grade on the following basis
Safe – 95% or greater chance of winning or all State’s EC votes allocated to one candidate in EC allocation
Strong – 70% to 95% chance of winning
Soft – 55% to 70% chance of winning
Tie – Less that 55% chance of winning for either candidate
Sites like FiveThirtyEight have a higher probability of Trump winning. What are you doing wrong?
Nothing! 538 uses a different methodology than we do and they are also producing a forecast of polling day
