Where the money comes from

Who gives to each campaign, and where those donors live, for this election (since 2025). Cash the state lists donor-by-donor.

Heather Sievers · Democrat

Who gives · this election (since 2025)

Individuals 70% ($59,294.18)PACs & committees 27% ($23,289.00)Other organizations 3% ($2,250.00)

Shares are of the $84,833.18 that donors gave this election (since 2025). Of the $23,289.00 from PACs and committees, $8,789.00 is from PACs, $12,000.00 from party committees and $2,500.00 from committees whose type isn't in the filings we hold (they file no Iowa disclosure report of their own, so the state's records we have don't say whether they are a PAC, a party or a candidate).

$2,000.00 is money the committee received under its own committee code, not a gift from anyone else; it is left out of the who-gives bar.

Where they live · this election (since 2025)

ZIP crosses the district line 17% ($14,856.97)Elsewhere in Iowa 53% ($46,373.97)Iowa, ZIP not mapped 5% ($4,500.00)Outside Iowa 24% ($21,102.24)

Between 0% and 17% of the $86,833.18 whose donor listed an address came from inside the district (House District 40) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

76% came from somewhere in Iowa and 24% from outside the state. $4,500.00 of the Iowa money has a ZIP code with no area on the map (a post office box, for example), so it can't be placed in or out of the district.

$86,833.18 in cash this election (since 2025), listed donor-by-donor in the state's itemized feed (the publisher dates the feed 2026-07-14, posted 2026-09-05). · full record →

Shares are of the $61,293.85 that donors gave this election (since 2025). Of the $21,950.00 from PACs and committees, $18,450.00 is from PACs and $3,500.00 from committees whose type isn't in the filings we hold (they file no Iowa disclosure report of their own, so the state's records we have don't say whether they are a PAC, a party or a candidate).

ZIP crosses the district line 19% ($11,719.03)Elsewhere in Iowa 71% ($43,424.82)Outside Iowa 10% ($6,150.00)

Between 0% and 19% of the $61,293.85 whose donor listed an address came from inside the district (House District 40) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

Its filings report $105,886.27 raised in cash this election (since 2025), and $61,293.85 of that is listed donor-by-donor. The bars use the donor-by-donor part. Its newest report (filed 2026-07-20, $44,592.42 raised, for the period ending 2026-07-14) is not yet in the donor-by-donor rows we hold, so the bars stop at the report before it. · full record →

Not in the bars: $12,132.67 in donated goods and services this election (since 2025).

Method: itemized cash contributions (Schedule A, transaction type CON) since 2025-01-01, refunds netted, the committee's own account interest excluded. Each donor is placed by the state and 5-digit ZIP code on the filing. A ZIP code counts as in the district when at least 98% of its Iowa land area (Census ZCTA) falls inside it, as crossing the line when between 2% and 98% does, and as elsewhere in Iowa otherwise. Iowa ZIP codes with no Census area (post office boxes) are shown on their own. In-kind support and loans are never in either bar.

Fundraising rate

New money raised per day of each candidate's latest report — the pace of fundraising, comparable even when reports cover spans of different length. The small bars trace how that pace moved across recent reports.

Bill Gustoff $731/day

$44,592.42 over 61 days · latest report

Heather Sievers $516/day

$31,504.49 over 61 days · latest report

Behind in total cash, Bill Gustoff is raising faster by the day right now — $731/day versus $516/day for Heather Sievers, the current cash leader.

Rate = money raised ÷ days the report covers. ("Money raised" is the report's cash-contribution line — Schedule A.) Faded bars are earlier reports' rates; the solid bar is the latest. State committees only. A period's total can arrive as one large check or many small gifts — the rate can't tell them apart; a committee's donation page breaks its money down by gift size.
