Polling Gives Edge to US Senate Challenger

The most-recent polling by Nexstar Iowa 2020 shows Democrat Theresa Greenfield leading Republican incumbent Joni Ernst by six points, 51-to-45 percent, less than a week before Election Day.  Greenfield has the edge on Ernst among both men and women.  No U-S Senator in Iowa has lost a re-election bid since Tom Harkin beat Roger Jepsen in 1984.
