Harry Explains the Forecast
What is the margin of error?
Look, we’re making a forecast. It’s not going to be perfect. Anything within this range could reasonably happen, though we expect the result to be close to our best estimate.
How does the prediction update?
The prediction updates every day as more polls come out. The prediction should become more accurate the closer we are to the election.
