Nate Silver:一个月前中期选举的民调预测准确性不高,误差范围可能远大于看起来的差距。以佛罗里达州为例,民主党候选人Val Demings落后共和党候选人Marco Rubio 6个百分点,但在仅基于民调的预测中,Demings的胜算只有20%。这意味着民调的误差范围可能远大于5个百分点。全国性选举的民调平均误差在4-5个百分点左右,总统选举和中期选举、以及不同级别的竞选(总统、国会)误差都不同,越往下的竞选误差越大。 Nate Silver:重大事件(如Dobbs裁决)对民调结果的影响需要时间才能体现出来。国会选举的民调变化幅度不如总统选举剧烈,因为国会选举的候选人不同,而且每个州的民调结果对其他州的影响较小。总统选举民调结果对全国范围内的预测更有参考价值,而国会选举则不然。模型会根据最新的民调结果调整预测结果,但调整的幅度和速度会受到多种因素的影响,例如:民主党放弃的选区数量、模型使用的通用选票与网站上显示的通用选票存在差异、以及民调结果与历史数据之间的差距。 Galen Druk:民主党在参议院的胜算过去一个月下降了约5个百分点,这是否意味着形势正在向共和党倾斜?
