Who Is Paying to Influence Iowa’s Five Federal Races?
Iowa votes on Tuesday, November 3, 2026, for one U.S. Senate seat and all four of its U.S. House seats. This almanac lists the outside groups that reported spending on ads, mail and other messages about those races, says whether each report supported or opposed a candidate, and links figures to their source records.
I. The Races
One U.S. Senate race and four U.S. House districts. The table is the way in: choose a race to open its chapter, or read its evidence plate below.
Where no filing is found, the evidence will say “No record found within current coverage”. It never shows that as $0.
The campaigns’ own reported totals come first, then what outside groups reported spending for or against each candidate; follow the card’s links to the filings.

No record found within current coverage is not the same as zero.

News dates show when an article was published. They are not spending-data dates.
IV. Field Notes
Where the numbers come from. Reports filed with the Federal Election Commission. After Citizens United collects them, checks them and publishes each with a link to its source record; this almanac embeds those evidence cards rather than copying the numbers.
Three dates, kept apart. When the filings were collected (UTC), the period each report covers, and when the dataset was published. News dates are separate from all three.
No record is not zero. “No record found within current coverage” means no filing was found in the period collected. It is not the same as $0; filings sent in later, or not yet processed, will not appear.
Left out: communications that need not be reported to the FEC (such as many issue ads), state and local races, lobbying, and spending reported after the collection date. Individual donors are not profiled.
