Pollster Ann Selzer reviews Iowa data after Harris leads Trump in controversial poll

Pollster Ann Selzer is reviewing her data after her Iowa poll inaccurately showed Vice President Kamala Harris leading former President Donald Trump just days before the election. The poll indicated a surprising 7-point shift in favor of Harris. The Des Moines Register/Mediacom poll, released shortly before the election, had Harris at 47% compared to Trump’s 44%. This was a significant change from September, when Trump led by 4 points. Trump ultimately won Iowa decisively. Selzer acknowledged the discrepancy, stating the poll results did not align with the actual voting outcome. She plans to analyze data from various sources to understand the reasons behind the inaccurate predictions.
