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.

Blaine Watkins · Republican

Who gives · this election (since 2025)

Individuals 67% ($16,074.00)PACs & committees 31% ($7,300.00)Other organizations 2% ($540.00)

Shares are of the $23,914.00 that donors gave this election (since 2025). Of the $7,300.00 from PACs and committees, $4,300.00 is from PACs, $2,000.00 from party committees and $1,000.00 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 11% ($2,595.00)ZIP crosses the district line 33% ($7,870.00)Elsewhere in Iowa 50% ($11,960.00)Iowa, ZIP not mapped 1% ($140.00)Outside Iowa 5% ($1,230.00)

Between 11% and 44% of the $23,795.00 whose donor listed an address came from inside the district (House District 100) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

95% came from somewhere in Iowa and 5% from outside the state. $140.00 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 $31,741.67 raised in cash this election (since 2025), and $23,914.00 of that is listed donor-by-donor. The bars use the donor-by-donor part. Its newest report (filed 2026-07-20, $8,327.67 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: $97,591.80 in donated goods and services this election (since 2025). The second bar also leaves out $119.00 from donors with no usable address on the filing.

Individuals 100% ($14,349.10)

Shares are of the $14,349.10 that donors gave this election (since 2025).

Where they live · this election (since 2025)

Between 20% and 86% of the $14,088.10 whose donor listed an address came from inside the district (House District 100) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

96% came from somewhere in Iowa and 4% from outside the state. $52.19 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.

$14,349.10 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: $3,016.24 in donated goods and services this election (since 2025) and $1,000.00 in loans the campaign received this election (since 2025), money it owes back and often the candidate's own. The second bar also leaves out $261.00 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.

Blaine Watkins $137/day

$8,327.67 over 61 days · latest report

Matthew Mohrfeld $53/day

$3,262.95 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.
