Galen Druke:本期节目讨论了2024年美国大选的最新民调结果,重点关注了安·塞尔策的爱荷华州民调以及《纽约时报》的战场州民调。塞尔策的民调显示哈里斯在爱荷华州领先,而《纽约时报》的民调显示结果并不一致,在一些州哈里斯领先,另一些州特朗普领先。节目还讨论了民调从众现象以及提前投票对选举结果的影响。 Mary Radcliffe:对民调平均值的解读需要谨慎,因为误差范围使得结果可能向任何一方倾斜。虽然民调显示选情胶着,但这并不意味着最终结果的差距会很小。民调从众现象可能源于民调机构有意操纵数据,也可能源于行业内普遍采用的方法导致结果相似。高质量民调数据显示哈里斯的支持率可能比包含所有数据的平均值更高。 Ruth Igielnik:民调结果过于接近,存在民调从众现象的可能性,尤其是在经验不足的民调机构中。高质量民调机构的数据显示哈里斯的支持率可能略高于低质量民调数据。安·塞尔策的爱荷华州民调结果与其他民调结果存在差异,是一个异常值,但其中也包含了一些值得关注的信息,例如白人选民对哈里斯的支持率有所提高。竞选后期发生的事件对最终投票结果的影响可能有限,因为提前投票的比例很高。 Mary Radcliffe:对民调平均值的解读需要谨慎,因为误差范围使得结果可能向任何一方倾斜。虽然民调显示选情胶着,但这并不意味着最终结果的差距会很小。民调从众现象可能源于民调机构有意操纵数据,也可能源于行业内普遍采用的方法导致结果相似。高质量民调数据显示哈里斯的支持率可能比包含所有数据的平均值更高。 Ruth Igielnik:民调结果过于接近,存在民调从众现象的可能性,尤其是在经验不足的民调机构中。高质量民调机构的数据显示哈里斯的支持率可能略高于低质量民调数据。安·塞尔策的爱荷华州民调结果与其他民调结果存在差异,是一个异常值,但其中也包含了一些值得关注的信息,例如白人选民对哈里斯的支持率有所提高。竞选后期发生的事件对最终投票结果的影响可能有限,因为提前投票的比例很高。 Ruth Igielnik:民调结果过于接近,存在民调从众现象的可能性,尤其是在经验不足的民调机构中。高质量民调机构的数据显示哈里斯的支持率可能略高于低质量民调数据。安·塞尔策的爱荷华州民调结果与其他民调结果存在差异,是一个异常值,但其中也包含了一些值得关注的信息,例如白人选民对哈里斯的支持率有所提高。竞选后期发生的事件对最终投票结果的影响可能有限,因为提前投票的比例很高。

Deep Dive

Key Insights

Why are the final polls showing a close race between Harris and Trump?

The polling averages indicate a close race due to small margins separating the candidates in key swing states. However, these averages suggest a probabilistic close race rather than a definitive one, meaning the outcome could still swing significantly in either direction.

What are the concerns about herding among pollsters?

Herding concerns arise when pollsters intentionally align their results with existing averages to avoid being outliers. This practice can distort the true picture of voter sentiment and reduce the variability that is crucial for understanding shifts in the electorate.

How does the Seltzer Iowa poll differ from other polls?

The Seltzer Iowa poll shows Harris leading Trump by three points, which is an outlier compared to other polls showing Trump ahead. This discrepancy could indicate a significant shift in Iowa or suggest methodological differences in how pollsters are adjusting their models post-2020.

What insights does the Seltzer poll provide about voter trends?

The Seltzer poll suggests potential shifts among white voters and older demographics towards Harris, indicating a closer race in Iowa than in 2020. It also highlights a significant gender gap and strong support among independent women, which could be indicative of broader trends.

How do the New York Times' final battleground polls compare to earlier ones?

The final New York Times polls show a slight shift towards Harris in the Sun Belt states and a tightening in the Rust Belt states like Pennsylvania. This contrasts with earlier polls that indicated a stark divide between these regions, suggesting a more competitive race overall.

What impact might the early voting data have on the election outcome?

Early voting data indicates a higher turnout among women, which could benefit Harris, especially given the increased salience of the abortion issue. However, caution is needed as this trend may not be sufficient to overcome other motivating factors for Trump supporters.

What are the key demographic trends Mary Radcliffe is interested in observing post-election?

Mary Radcliffe is keen to see if trends observed in 2022, such as shifts in traditionally reliable states like New York and California, continue into 2024. These trends could reshape the electoral landscape in future elections.

Shownotes Transcript

Polls were coming in hot and heavy over the weekend! In fact, 164 surveys were entered into the 538 database since Friday. In this Election Day eve episode of the 538 Politics podcast, Galen Druke speaks with senior researcher Mary Radcliffe and New York Times polling editor Ruth Igielnik about what we are seeing in those final polls.

They discuss the famed Iowa Poll from Ann Selzer, which showed a rosy picture for Harris, and the battleground polling from the New York Times, which showed results that frustrate some of the trends we've come to expect this cycle. They also share some final thoughts on the election in the run up to the big day.
