2026 Iowa federal ballot

Iowa votes on a U.S. Senate seat and all 4 U.S. House seats on November 3, 2026.

What else is on your ballot

Federal races only, not governor, state or local contests or ballot measures. Iowa publishes sample ballots through local election offices rather than one statewide tool, so start at the County Auditor List, run by the Iowa Secretary of State.

The widest one reaches

31states

Independent spending filed on Iowa's races, by whether the committee is also spending in other states this cycle. A filing records where a group spends, not where its donors live, so this is a measure of reach, never of who paid for it.

Who is spending on Iowa

$104M outside money

The groups spending independently on Iowa's races, by what they have filed. Open a row to see how the money was spent, supporting or opposing each party, and the interest behind the committee.

Every race on the ballot

Each row names the November ballot on record; the filed count is every candidate on file with the FEC, not counting those who withdrew, retired or died. Each row opens the full field, the money, and the outside spending for that seat.
