The2020 United States presidential election in Iowa was held on Tuesday, November 3, 2020, as part of the2020 United States presidential election in which all 50 states plus theDistrict of Columbia participated.[1]Iowa voters chose electors to represent them in theElectoral College via a popular vote, pitting theRepublican nominee, incumbent PresidentDonald Trump of Florida, and his running mate Vice PresidentMike Pence ofIndiana againstDemocratic nominee, former Vice PresidentJoe Biden ofDelaware, and his running mate California SenatorKamala Harris. Iowa has six electoral votes in the Electoral College.[2]
Trump won the state 53.1% to Biden's 44.9%. Prior to this election, most news organizations had considered Iowa as either leaning towards Trump or a tossup. As was the case inOhio, this election has confirmed Iowa's trend from aMidwesternswing state toward the GOP column, the same trend as neighboringMissouri starting in2008. Iowa had voted Democratic in six of seven elections prior to 2016, the exception beingGeorge W. Bush's narrow plurality win in2004. In 2016, however, Iowa voted for Trump by an unexpectedly large margin of 9.4%, voting over ten points to the right of the nation overall, indicating a possible realignment of the previously Democratic-leaning state towards the GOP, much as in the case ofWest Virginia in2000 and2004. Even though Biden contested the state,[3] Trump ended up carrying it by only a slightly reduced margin of 8.2% even as his national margin of defeat grew by 2.4%, meaning that the state voted even further to the right of the national average than it did in 2016.
This marked the first time since2000 that the state voted for the national loser, and the first since1988 that it voted for the loser of the popular and electoral vote. Biden improved onHillary Clinton's margins in theDes Moines andCedar Rapids metropolitan areas and traditionally conservative western Iowa, the latter of which bordersNebraska's 2nd congressional district (Omahametropolitan area), an electoral vote Trump won in2016 but lost in2020. Trump improved on his2016 performance inpopulist northeast and south Iowa and became the first Republican to win Iowa in back-to-back elections sinceRonald Reagan in1980 and1984. Biden also became the first Democrat to be elected president without winning Iowa sinceJimmy Carter in1976. This is also the first time since2004 that Iowa voted for a different candidate than neighboringWisconsin.
Iowa is one of only three states that voted twice forBarack Obama and thrice for Trump, the other two beingFlorida andOhio.
The state's caucuses, traditionally the first major electoral event in the country, were held on February 3, 2020.[4]
Incumbent presidentDonald Trump received about 97 percent of the votes in the Republican caucuses, and received 39 of the Republican delegates, whileBill Weld received enough votes to clinch 1 delegate.[5]

Perexit polling by theAssociated Press, Trump's strength in Iowa came fromWhite Iowans with no college degree, who comprised 62% of the electorate and supported Trump by 58%–40%. Trump also dominated amongstChristian voters, garnering 66% ofProtestants, 54% ofCatholics, and 76% ofborn-again/EvangelicalChristians. 53% of voters believed Trump was better able tohandleinternational trade.[88] Trump continued to win the cultural message among voters without college degrees in Iowa.[89]
During the primary season, there remained hope among Democrats that Iowa would still be a contestable state.[90] However, Trump's well-held victory in the state in the general election also saw Republican congressional candidates—fromSenatorJoni Ernst to twoHouse seats, both held by Democrats (one vacated byDave Loebsack inIowa's 2nd district)—winning their election.
Neither Biden nor Trump flipped any counties in the state, although Biden came within 2% of flippingDallas County, a suburb ofDes Moines.Jefferson County was also very close, having gone for Trump by a similarly tight margin four years earlier.
