More Iowans than ever participated in the 2020 primary, and the event changed some features of the Iowa electorate. For the first time in at least 20 years, people who choose not to affiliate with any party don’t comprise a plurality of registered voters. Democrats and Republicans both outnumber no-party voters now.
In other ways, the 529,586 Iowans who cast ballots in the June 2 election resembled past primary voters. For instance, nearly three-quarters of them were at least 50 years old, while about 13 percent were under age 35. Those proportions by age group are remarkably close to corresponding figures from the 2018 primary, when only 288,749 Iowans voted.
