a retired U.S. Navy admiral and former aide to U.S. Senator Ted Kennedy. Polls conducted after the primary showed a close contest between Greenfield and Ernst. In early September, political handicappers The Cook Political Report and Sabato's Crystal Ball rated the race as a toss-up. Major media described the race as one of the most likely to decide control of the Senate after the 2020 election. Through June 30, 2020, Greenfield had raised $11.5 million, compared to $14.6 million for Ernst. In the third fundraising quarter, Greenfield's campaign raised $28.7 million, more than any Senate candidate in Iowa history. As of October 2020, the race was expected to be the most expensive in the state's history, and the second most expensive Senate race in the United States, after the 2020 United States Senate election in North Carolina. Greenfield received endorsements from former President Barack Obama, Minnesota Senator Amy Klobuchar, Massachusetts Senator Elizabeth Warren, Representative Abby Finkenauer, Representative Dave Loebsack, former Iowa first lady and education advocate Christie Vilsack, and former Lieutenant Governor of Iowa Sally Pederson. She was endorsed by organizations including the Iowa AFL-CIO, Iowa IBEW State Conference, EMILY's List, End Citizens United, and Giffords. In the general election on November 3, 2020, she was defeated by incumbent Ernst, winning only 8 of the state's 99 counties and an estimated 7 points behind the incumbent. Greenfield conceded the race in a speech that night and on her Twitter account the following day.
