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.

Brad Magg · Democrat

Who gives · this election (since 2025)

Individuals 96% ($29,409.27)PACs & committees 3% ($1,000.00)Other organizations <1% ($100.00)

Shares are of the $30,509.27 that donors gave this election (since 2025). Of the $1,000.00 from PACs and committees, $1,000.00 is from party committees.

Where they live · this election (since 2025)

In the district 11% ($3,247.00)ZIP crosses the district line 49% ($14,939.00)Elsewhere in Iowa 20% ($5,955.00)Iowa, ZIP not mapped <1% ($86.00)Outside Iowa 20% ($6,125.27)

Between 11% and 60% of the $30,352.27 whose donor listed an address came from inside the district (House District 38) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

80% came from somewhere in Iowa and 20% from outside the state. $86.00 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.

$30,509.27 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 →

Not in the bars: $2,072.39 in loans from before this election (2023 to 2024), money it owes back and often the candidate's own. The second bar also leaves out $157.00 from donors with no usable address on the filing.

Its filings report $7,170.64 raised in cash this election (since 2025), and $6,368.24 of that is listed donor-by-donor. The bars use the donor-by-donor part. Its newest report (filed 2026-07-18, $802.40 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: $100.00 in loans the campaign received this election (since 2025), money it owes back and often the candidate's own.

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.

Brad Magg $142/day

$8,688.46 over 61 days · latest report

Matthew Oleson $13/day

$802.40 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.
