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.

Kerry Gruenhagen · Republican

Who gives · this election (since 2025)

Individuals 18% ($3,650.00)PACs & committees 82% ($16,250.00)

Shares are of the $19,900.00 that donors gave this election (since 2025). Of the $16,250.00 from PACs and committees, $13,750.00 is from PACs 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).

Where they live · this election (since 2025)

In the district 3% ($600.00)ZIP crosses the district line 12% ($2,350.00)Elsewhere in Iowa 69% ($13,700.00)Outside Iowa 16% ($3,250.00)

Between 3% and 15% of the $19,900.00 whose donor listed an address came from inside the district (Senate District 41) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

84% came from somewhere in Iowa and 16% from outside the state.

$19,900.00 in cash this election (since 2025), listed donor-by-donor. Its newest report (filed 2026-07-20, $100.00 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 →

Tom Wieck · Democrat

Who gives · this election (since 2025)

Individuals 96% ($11,500.24)PACs & committees 4% ($500.00)

Shares are of the $12,000.24 that donors gave this election (since 2025). Of the $500.00 from PACs and committees, $500.00 is from party committees.

Where they live · this election (since 2025)

In the district 18% ($2,070.00)ZIP crosses the district line 25% ($2,885.00)Elsewhere in Iowa 26% ($3,086.00)Iowa, ZIP not mapped 2% ($200.00)Outside Iowa 30% ($3,514.24)

Between 18% and 42% of the $11,755.24 whose donor listed an address came from inside the district (Senate District 41) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

70% came from somewhere in Iowa and 30% from outside the state. $200.00 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.

Its filings report $12,225.24 raised in cash this election (since 2025), and $12,000.24 of that is listed donor-by-donor in the state's itemized feed (the publisher dates the feed 2026-07-14, posted 2026-09-05). The bars use the donor-by-donor part. · full record →

The second bar also leaves out $245.00 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.

Tom Wieck $51/day

$3,121.45 over 61 days · latest report

Kerry Gruenhagen $1.6/day

$100.00 over 61 days · latest report

Behind in total cash, Tom Wieck is raising faster by the day right now — $51/day versus $1.6/day for Kerry Gruenhagen, 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.
