Who Will Be President?

The Upshot’s elections model suggests that Hillary Clinton is favored to win the presidency, based on the latest state and national polls. A victory by Mr. Trump remains quite possible: Mrs. Clinton’s chance of losing is about the same probability that an N.B.A. player will miss a free throw.

From now until Election Day, we’ll update our estimates with each new poll, as well as collect the ratings of other news organizations. You can chart different paths to victory below. Here’s how our estimates have changed over time:

To forecast each party’s chance of winning the presidency, our model calculates win probabilities for each state. In addition to the latest state polls, our forecast incorporates a state’s past election results and national polling.

The table below shows our model’s estimate for Democrats and Republicans in all 50 states and Washington, D.C. We have put the states into five groups based on their voting history relative to the nation since 2004.

The New York Times is one of many news organizations to publish election ratings or forecasts. Some, like FiveThirtyEight or the Princeton Election Consortium, use statistical models, as The Times does; others, like the Cook Political Report, rely on reporting and knowledgeable experts’ opinions. PredictWise uses information from betting markets.

We compile and standardize these ratings every day into one scoreboard for comparison. First, every organization’s estimate for who will win the presidency:

Second, each organization’s state-by-state ratings. Viewed together, the differences between the models become much clearer.

Some combinations of electoral votes are much more common than others. The chart below shows the estimated likelihood of each outcome.

The interactive diagram below illustrates Mr. Trump’s challenging path to the presidency. Here, we assume Mrs. Clinton and Mr. Trump will win the states where we believe they are most strongly favored, and we let you control the outcome of the 10 most competitive states. Above all, this diagram illustrates how important Florida is to Mr. Trump. It is extremely difficult for him to win without it.
