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 Matson · Democrat

Who gives · this election (since 2025)

Individuals 58% ($46,986.87)PACs & committees 38% ($30,604.32)Other organizations 5% ($4,000.00)

Shares are of the $81,591.19 that donors gave this election (since 2025). Of the $30,604.32 from PACs and committees, $1,000.00 is from PACs and $29,604.32 from other candidates' campaigns.

Where they live · this election (since 2025)

ZIP crosses the district line 51% ($41,397.68)Elsewhere in Iowa 30% ($24,089.33)Iowa, ZIP not mapped 5% ($4,041.67)Outside Iowa 15% ($12,062.51)

Between 0% and 51% of the $81,591.19 whose donor listed an address came from inside the district (Senate District 21) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

85% came from somewhere in Iowa and 15% from outside the state. $4,041.67 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.

Its filings report $147,851.29 raised in cash this election (since 2025), and $81,591.19 of that is listed donor-by-donor. The bars use the donor-by-donor part. Its newest report (filed 2026-07-17, $66,260.10 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 →

Between 0% and 40% of the $15,404.68 whose donor listed an address came from inside the district (Senate District 21) 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 newest report (filed 2026-07-20, $1,060.82 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: $1,023.37 in donated goods and services this election (since 2025). The second bar also leaves out $50.00 from donors with no usable address on the filing.

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.

Heather Matson $1,086/day

$66,260.10 over 61 days · latest report

John Hollinrake $17/day

$1,060.82 over 61 days · latest report

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.
