Pollsters have had a rough time accurately forecasting elections with Donald Trump at the helm, but in 2024, they finally seemed to have cracked the code. After missing the mark in both 2016 and 2020, where they consistently underestimated Trump’s level of support, the polls in 2024 landed within the margin of error for aggregate predictions.
The key to this success, according to pollsters, was finally figuring out how to reach and engage with Trump voters. In the past, many Trump supporters simply refused to participate in polls, leading to skewed results. GOP pollster Whit Ayres noted that when pollsters called Trump supporters, they often met with resistance and refusal to answer questions, making it challenging to accurately gauge their level of support.
While the polls in 2024 were more accurate overall, there were still some notable flubs. Renowned pollster Ann Selzer, known for her accuracy, faced criticism after her firm released a poll showing Vice President Kamala Harris leading Trump in Iowa, only for Trump to ultimately win by a significant margin.
Since the 2016 election, pollsters have struggled with undercounting Trump’s base, a unique challenge that arises when Trump is on the ticket. Trump’s base tends to distrust institutions and can be difficult to survey, especially in presidential election years when turnout is higher.
To correct course in 2024, researchers made adjustments to their modeling of the likely electorate, weighted certain demographic groups more heavily, and refined their outreach strategy to reach more non-college-educated voters who lean Republican. These efforts resulted in more accurate predictions, with final polling aggregates showing tight races in swing states and Trump ultimately sweeping all the battlegrounds.
One surprising outcome was the undecided voters breaking unevenly in Trump’s favor, contributing to his decisive victory. Pollsters noted that undecided voters traditionally did not favor Republicans, making this shift unexpected.
While the polls on election night aligned with aggregate predictions, they still tended to undercount Trump’s support by about 3 points. This discrepancy could be attributed to voters making last-minute decisions, with Trump benefiting from a surge in support following a late endorsement from Joe Rogan.
Looking ahead to future elections, pollsters are divided on whether the challenges of accurately forecasting elections will persist without Trump in the mix. Some, like Ayres, are optimistic that the issues related to reaching Trump voters will fade away. However, others, like Democratic pollster Paul Maslin, believe that the question of polling accuracy will continue to be an ongoing challenge that requires close attention and refinement.
Overall, while the polls in 2024 were more accurate than in previous years, the task of predicting election outcomes remains a complex and ever-evolving process that will require ongoing scrutiny and adaptation.
