The U.S. Senate race between Republican Joni Ernst and Democratic challenger Theresa Greenfield is the most expensive one in Iowa’s history. It’s also one of the most competitive races in the country and could decide what party controls the chamber.
“This is the second most expensive senate race when we combine candidate and outside spending this year behind only North Carolina,” says Jessica Taylor with The Cook Political Report. “I think this just goes back to how critical this is in who will determine the Senate.”
Campaign finance tracking website OpenSecrets.org says $217 million dollars has been spent on the race so far.
Sen. Ernst and Greenfield have been locked in a tight race for months and the two are spending their final days before Election Day working to get out the vote in their favor.
