Final Iowa poll: Joni Ernst pulls ahead in final days of Senate race

Ernst leads 46% to 42% over Greenfield, the Iowa Poll shows. Another 3% say they plan to vote for someone else, 1% do not plan to vote in the Senate race, 3% are unsure and 4% already voted but did not want to say which candidate they support…

“It’s really both a matter of Ernst rising and Greenfield fading a little bit,” said J. Ann Selzer, president of Selzer & Co. “There’s sort of an equilibrium in terms of what’s happening.”

This is the final 2020 Iowa Poll before the election, and it’s the first time Ernst has led in the poll this year.

In June, Greenfield led Ernst by 3 percentage points, 46% to 43%. In September, Greenfield maintained that 3-percentage-point lead, 45% to 42%. The margin of error for both of those polls was plus or minus 3.8 percentage points.
