How has the forecast changed in Iowa over time?
The forecast updates at least once a day and whenever we get new data. Uncertainty will decrease as we get closer to Election Day.
We forecast the popular vote only for candidates polling at 5 percent or higher nationally, polling at 10 percent or higher in at least one state or who are on the ballot in almost every state. Since Robert F. Kennedy Jr.’s withdrawal, only Harris and Trump meet these criteria, so we are effectively forecasting the two-way popular vote between Democrats and Republicans.
What do the polls or fundamentals alone say?
Our forecast is based on a combination of the polls and various economic and political variables we call the “fundamentals.” This chart shows how we get from the polls today to a forecast for [state] on Election Day.
Polling average
The state of public opinion today, according only to 538’s average of polls in [state] and accounting for trends in national polls.
Adjusted polling average
The polling average for [state] adjusted for movement in similar states and the effects of party conventions.
Forecast of polling average on Election Day
The adjusted polling average with uncertainty intervals that account for potential movement in the race between now and Election Day. This does not account for the chance that the polls systematically underestimate one candidate.
