Respected Iowa pollster J. Ann Selzer responded Monday to the attacks launched against her by Donald Trump after her bombshell poll showed him trailing in the state.

The Des Moines RegisterA /Mediacom poll conducted by Selzer and released Saturday showed Kamala Harris leading Trump by three points — 47 percent to 44 percent — in Iowa, a state he won handily in 2016 and 2020. It may have been for Trump worrisome given Selzer’s track record of accurately predicting outcomes in the Hawkeye State.

Trump was so concerned by the poll that he posted about it on Truth Social, claiming that all polls “except one, which was heavily biased toward Democrats by a Trump hater,” showed him in the lead. “I have a 10-point lead in Iowa,” he said during a campaign stop in Pennsylvania on Sunday. “One of my enemies just published a poll – I’m three points lower.”

“They just announced a fake poll,” he continued. “Hey, remember – right before the election – I’m three points behind. I’m not down in Iowa.” Trump’s campaign separately released a memo called Selzer’s poll “a clear outlier” and pointed it out Emerson College Survey was released the same day, giving Trump a 10-point lead over Harris.

During an appearance Monday on MSNBC Morning JoeSelzer admitted that the results of her survey were a “shock.”

“I’ve been shocked since Tuesday morning last week,” Selzer said. “So I had the time to memorize that because no one, including me, thought Iowa could go for Kamala Harris.”

Co-host Willie Geist specifically asked Selzer about Trump’s criticism and asked her to respond to the claim that her poll was just an outlier.

“I honor my track record with my method,” Selzer said. “I call my method ‘Polling Forward.'” That’s why I want to be in a place where my data can show me what’s likely to happen to the future electorate. So I just try to get out of the way of my data and say this is what’s going to happen.”

“Many other surveys, and I include Emerson, take into account things that have happened in the past in the way they manipulate the data once they come in,” she continued. “So they take election polls into account, they take into account voter turnout in past elections. I don’t make such assumptions. In my opinion it is a cleaner way to predict a future electorate that no one knows what it will look like. But we know that our electorate changes depending on the number and composition of voters.”

Selzer later added that the method she used to reach those results did not change from the one she used in previous presidential elections, in which Trump prevailed in Iowa.

“This method is the same method we used in 2016 to show Trump winning and in 2020 to show Trump winning,” she said. “So he doesn’t like it now – it’s not the poll, it’s what the poll says.”
