2020 United States Senate election in Iowa
The 2020 United States Senate election in Iowa was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Iowa, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections. Primaries were held on June 2.[1] Most experts and pollsters considered this race as well as the presidential race as a tossup, but both Republican presidential candidate Donald Trump and Ernst won a larger margin than expected.

Democratic primary
On June 2, 2020, Theresa Greenfield won the Democratic primary with 47.71% of the vote, defeating three other major candidates, including Michael T. Franken, a retired U.S. Navy admiral and former aide to U.S. Senator Ted Kennedy.[9][10][11][12][13]
Greenfield grew up on a small farm where her family raised raised crops and hogs.[14] She took courses at Iowa Lakes Community College and Iowa State University before graduating from Minnesota State University, Mankato in 1987 with a bachelor's degree in design and human environment.[15] At 24 years old, Greenfield's husband, an electrician, was killed in a work accident.[16][17] She has credited Social Security, workers' compensation, and family support with helping her through that period, during which she was caring for a one-year-old son and pregnant with a child born five months later.[17][18][19][20]
In 2005, Greenfield took a position at the homebuilding company Rottlund Homes, where she was named president of the Iowa division in 2007.[21] In 2012, Greenfield became president of the Des Moines commercial real estate firm Colby Interests,[22] based in Windsor Heights, Iowa.[20]

General election
Major media described the campaign as one of the most likely to decide control of the Senate after the 2020 election.[65][66] Polls conducted after the primary showed a close contest between Greenfield and Ernst, with neither candidate leading by more than 4 points.[67][68][69][70] As of September 5, 2020, political handicappers The Cook Political Report and Sabato's Crystal Ball rated the race as a toss-up.[71][72]
Through June 2020, Greenfield had raised $11.5 million, compared to $14.6 million for Ernst but by September, Greenfield had pulled ahead, raising $40.0 million compared to $21.6 million for Ernst.[73][74][75] The race was expected to be the most expensive in the state's history,[76] and the second most expensive Senate race in the United States, after the 2020 United States Senate election in North Carolina, where Cal Cunningham challenged Thom Tillis.[77]
On October 17, the Des Moines Register endorsed Greenfield.[78]
