We'll be updating our forecasts every time new data is available, every day through Nov. 8.

Who’s ahead in each state and by how much

Our win probabilities come from simulating the election 10,000 times, which produces a distribution of possible outcomes for each state. Here are the expected margins of victory. The closer the dot is to the center line, the tighter the race. And the wider the bar, the less certain the model is about the outcome.

Here's a map of the country, with each state sized by its number of electoral votes and shaded by the leading candidate's chance of winning it.

Key

One electoral vote

A candidate needs at least 270 electoral votes to clinch the White House. Here's where the race stands, with the states ordered by the projected margin between the candidates — Clinton’s strongest states are farthest left, Trump’s farthest right — and sized by the number of electoral votes they will award.

Two measures help capture how important a state and its voters will be in determining the next president: “Tipping-point chance” is the probability that a state will provide the decisive vote in the Electoral College. “Voter power index” is the relative likelihood that an individual voter in a state will determine the Electoral College winner.

In each of our simulations, we forecast the states and note the number of electoral votes each candidate wins. That gives us a distribution for each candidate, where the tallest bar is the outcome that occurred most frequently.

Who’s winning the popular vote

Our model produces a distribution of outcomes for the national popular vote. The curves will get narrower as the election gets closer and our forecasts become more confident.
