Early voting won’t begin in Iowa until October 5, but signs already point to a high-turnout election, with many more Iowans casting early ballots than in the past. By September 25, more than five weeks before this year’s election, 583,944 people–more a quarter of Iowa’s 2 million active registered voters–had requested an absentee ballot. That number doesn’t include anyone planning to vote early in person next month.

Just before the 2016 presidential election, 693,709 Iowans had requested absentee ballots, and county auditors had received 653,438 completed ballots. We should surpass that number well before November 3. About 41 percent of Iowans voted early in 2016, but the COVID-19 pandemic will surely push that percentage higher.

I will update this page every weekday with the latest absentee ballot numbers released by the Iowa Secretary of State’s office, presented in two tables.

In the clearest sign yet that the business establishment is preparing for a Democratic administration in Washington, the U.S. Chamber of Commerce will endorse 23 first-term House Democrats, including U.S. Representatives Abby Finkenauer (IA-01) and Cindy Axne (IA-03).

Alex Gangitano was first to report the planned endorsements for The Hill on September 1. Other political reporters soon confirmed the news.

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.

Follow me after the jump for a closer look at this year’s expanded voter universe by party, gender, and age.

July 6 was the first day Iowans can request an absentee ballot for the 2020 general election. Under normal circumstances, I prefer voting early in person and have encouraged others to do the same. But voting by mail is by far the safest option for 2020, in light of the COVID-19 pandemic.

Republican legislators signaled last week they won’t allow Secretary of State Paul Pate to send absentee ballot request forms to every registered voter again.

Election officials in Iowa’s largest counties aren’t waiting to see how things play out. Several auditors are already making plans for their own universal mailings. Higher turnout in those counties should benefit Democratic candidates for federal offices and state legislative seats.

Secretary of State Paul Pate will need approval from the Legislative Council in order to use his emergency powers to alter election procedures, under a bill Governor Kim Reynolds signed on June 25.

While Republicans have a majority on that legislative body, it’s not clear they would use that power to prevent Pate from repeating steps that led to record-breaking turnout for the June 2 primary.

The fields are set for Iowa’s 2020 federal campaigns. The U.S. Senate race and three out of four House races could be highly competitive this November. However, Democratic prospects for picking up the fourth Congressional district took a big hit last night.
