Henry Olsen: political analyst on Kamala Harris beating out Donald Trump in Iowa poll - Heather du Plessis-Allan Drive

There's questions whether polls from Iowa will affect Republicans on election day.

Donald Trump previously won the state in 2016 and 2020 - but is three percentage points behind Democratic candidate Kamala Harris 

Political analyst Henry Olsen says those figures seem out of step with Iowa's usual trend.

"I can see Trump doing a little worse, but it's hard to see Trump losing a state that he carried by 8 points in 2020."

Olsen is predicting Trump will re-enter the White House.

More than 78 million Americans have already cast votes ahead of polling day on Wednesday, New Zealand time.
