Iowa: Trump 47, Biden 47

“I don’t know that there’s any race in the history of presidential polling in Iowa that shows this kind of division,” said J. Ann Selzer, president of Selzer & Co., the firm that conducted the poll.

Trump leads by 21 percentage points with men, 57% to 36% over Biden. And Biden leads by 20 percentage points with women, 57% to 37% over Trump…

CNN exit polling of Iowa voters in the 2016 election showed Trump carried men by 28 percentage points, 61% to 33%. Democrat Hillary Clinton carried women, but by a smaller margin than Biden is now — just 7 percentage points, or 51% to 44%.

That migration of women over to Biden is a major factor driving the current race dynamics, Selzer said.
