Why do the polls keep misfiring?
Francesca Hong was riding high. The last five polls in Wisconsin’s gubernatorial contest had her winning by as many as 22 percentage points. She lost narrowly, and so did the pollsters.
TL;DR
- Recent polls in Wisconsin and Michigan mispredicted election outcomes, with Francesca Hong and Abdul el Sayed losing narrowly despite favorable polling.
- Primary elections are notoriously difficult to poll, with an average error of 13 points in past analyses.
- Challenges include accurately estimating turnout, the composition of the electorate, and late-breaking voter sentiment, especially in open primaries.
- While efforts are being made to improve polling accuracy after issues in 2020 and 2024, experts expect continued failures.
- Conducting high-quality polls requires extensive resources, as demonstrated by a New York Times/Sienna poll that made over 467,000 calls to more than 174,000 voters.
- Government surveys face issues with declining response rates, increasing costs, and budget cuts, impacting data reliability.
- Increasing paid incentives for surveys has been found not to decrease survey quality, offering a potential solution for response rates.
- Failures in election polling may negatively affect people's willingness to participate in other surveys, impacting vital national statistics.
