Vice President Kamala Harris leads former President Donald Trump by three percentage points in Iowa in a new poll, the Des Moines Register reports.

The poll shows Kamala Harris has 47% of support from likely voters compared to Donald Trump’s 44%.

Women voters, particularly older women, make up the increase in support for Harris.

The Iowa Poll results from September showed Trump with a 4% lead over Harris.

“It’s hard for anybody to say they saw this coming,” said pollster J. Ann Selzer, president of Selzer & Co, The Des Moines Register reported. “She has clearly leaped into a leading position.”

The poll, conducted by the Des Moines Register and Mediacom Iowa Poll, included 808 Iowa voters. It has a margin of error of 3.4 percentage points.

Trump won Iowa with a significant lead in 2016 and 2020, and neither candidate has prioritized campaigning in Iowa this year, instead focusing on seven battleground states.

“Age and gender are the two most dynamic factors that are explaining these numbers,” Selzer said.

Independent women voters supported Harris by a 28-point margin in the poll. Senior women voters supported Harris 68% to 28% for Donald Trump.

Trump recently pulled ahead of Harris in Atlas Intel’s poll conducted Oct. 30-31, which had the former president at 49.1% compared to the VP at 47.2% in an expanded field that includes third-party candidates. Trump maintains his lead in a head-to-head matchup, leading 49.6% to 48.2%.

Allen Lichtman, a historian and election forecaster who has successfully predicted the last nine out of 10 presidential elections, is sticking with his forecast that shows a Harris win. Known as the “Nostradamus” of elections, the latest forecast matches his earlier predictions, USA Today reported, despite the Vice President’s lead in battleground states shrinking and polls that show a neck-and-neck race.
