Theresa Greenfield defeated Michael Franken, Kimberly Graham, and Eddie Mauro to win the Democratic primary for U.S. Senate in Iowa on June 2, 2020. Greenfield won 47.8% of the vote to Franken's 25.0%, Graham's 15.0%, and Mauro's 11.0%. Had no candidate received more than 35% of the vote, the Democratic nominee would have been decided at a June 13 party convention.[1]

Greenfield was a real estate developer backed by the Democratic Senatorial Campaign Committee, EMILY's List, and 21 unions including the Iowa AFL-CIO.[2] In a campaign ad, she said that her support from labor unions and Democratic Party leaders showed that "she has what it takes to defeat Joni Ernst and hold Trump accountable."[3]

Franken, a retired vice admiral in the U.S. Navy, said that his "rural upbringing, 37 years of military service, and proven track record of distinguished leadership make him the Democrat to beat Joni Ernst."[4] He received endorsements from The Des Moines Register and former U.S. Secretary of Defense Chuck Hagel (R).[5][6]

Graham, an advocate and attorney for children in juvenile court, said, "We need more people from working-class backgrounds serving in government, representing the majority of us and not mega-corporations."[7] She received endorsements from Brand New Congress and the National Organization for Women.[8]

Mauro owned an insurance company. He said he "built a progressive business that provides paid family leave, where 65% of leadership are women." He added that "during the Great Recession, [he] took a pay cut [and] didn't lay off any employees."[9] Mauro received endorsements from state Reps. Ruth Ann Gaines (D-32), Ako Abdul-Samad (D-35), Ras Smith (D-62), and Charlie McConkey (D-15).[10]

A fifth candidate, Cal Woods, appeared on the ballot. Woods unofficially withdrew from the primary on May 4, 2020, and endorsed Franken.[11]

The general election was expected to be competitive. Incumbent Sen. Joni Ernst (R) ran for re-election. Ernst was first elected in 2014 following the retirement of Sen. Tom Harkin (D). She defeated Bruce Braley in the general election 52-44%. Heading into the election, Iowa had 31 pivot counties, which were counties that voted for Donald Trump (R) in 2016 after voting for Barack Obama (D) in 2008 and 2012. These counties accounted for 26% of the state's population.

During the 2018 midterm elections, Democratic candidates defeated Republican incumbents in two of Iowa's four Congressional Districts, switching the partisan control of U.S. House seats in the state from a Republican 3-1 majority to a Democratic 3-1 majority. In 2020, Democrats sought control of the U.S. Senate, where Republicans held a majority with 53 seats to Democrats' 45. Two independents caucused with Democrats.

Submitted Biography "I'm a retired vice admiral running for United States Senate to defeat Joni Ernst. I was born in rural Iowa. I spent the 80s and sea, the 90s in Washington D.C, and the 2000s fighting our wars on terror from the field and the capitol. I have a career of leading and succeeding around the world. In 2002, I was the only member of the Iraq War planning board to vote no on that war. That was a bad war then, and it remains one. If there had been courage in that room, perhaps our history would be different. When Donald Trump was elected, I retired because I did not want to work for Donald Trump. And in 2018, I knew I had to run for office because if he wins again, we had best own the Senate. I'm running to provide principled, experienced leadership for Iowans and Americans."

Submitted Biography "I'm a single mom with a 20-year son, Max. For 20 years I've also been an advocate and attorney for abused or neglected kids and parents in juvenile court. I'm running for office for Max, for all the kids I've represented, for all of us. Because it's time that one of us, represented us. My dad was one of 15 kids from a poor family. My mom was a teenager when she had me, dropped out of high school, then later got her GED. My parents lucked out, both found union jobs and retired from those jobs. My grandfather, my son's father and stepdad were or are all union workers. I was a union reorganized volunteer with the APFA, the American Airlines flight attendants' union. I've walked a picket line and fought for better wages and conditions for flight attends. We need more and stronger unions, too. Unions are one way we help balance power between workers and companies and it's hp we grow the middle class. I've been working non-stop since I was 14. I've waitressed, cleaned houses, worked in a dry cleaner, a retail store, and been a teacher and a teaching assistant. I worked 3 part-time jobs at times while in college until I became a flight attendant and then I worked all weekends and went to school during the week. I wanted to help people for a living, went to law school and took out student loans that I'm still paying on. I know what it's like to work hard in the wealthiest nation on earth and still not get ahead. America can do better and we will flip the Senate."

Primaries in Iowa

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. In Iowa, a voter must be affiliated with a party in order to participate in its primary. However, a voter can change his or her political party affiliation on Election Day, creating what is effectively an open primary.[41]

For information about which offices are nominated via primary election, see this article.

What's at stake in the general election?

U.S. Senate elections were held on November 3, 2020, and coincide with the 2020 presidential election. Thirty-three of the Senate's 100 seats were up for regular election in November. There were also two special elections in 2020. The results determined control of the U.S. Senate in the 117th Congress.

At the time of the election, the Republican Party had a 53-seat Senate majority, while Democrats had 45 seats. There were also two independents who caucus with the Democratic Party. Republicans faced greater partisan risk than Democrats in 2020 because they were defending 23 seats compared to 12 for the Democrats. Both parties had two incumbents representing states the opposite party's presidential nominee won in 2016.

In 2018, Democrats and Democratic-caucusing independents defended 26 of the 35 seats up for election, while Republicans defended the other nine. Republicans won 11 seats to the Democrats' 24, for a GOP net gain of two.

In the 24 previous Senate elections that coincided with a presidential election, the president's party had gained Senate seats in 16 elections and lost seats in nine. In years where the president's party gained seats, the average gain was three seats. In years where the president's party lost seats, the average loss was five seats.

General election race ratings

See also: Race rating definitions and methods

Ballotpedia provides race ratings from four outlets: The Cook Political Report, Inside Elections, Sabato's Crystal Ball, and DDHQ/The Hill. Each race rating indicates if one party is perceived to have an advantage in the race and, if so, the degree of advantage:

  • Safe and Solid ratings indicate that one party has a clear edge and the race is not competitive.
  • Likely ratings indicate that one party has a clear edge, but an upset is possible.
  • Lean ratings indicate that one party has a small edge, but the race is competitive.[42]
  • Toss-up ratings indicate that neither party has an advantage.

Race ratings are informed by a number of factors, including polling, candidate quality, and election result history in the race's district or state.[43][44][45]
