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.

Barb Kniff McCulla · Republican

Who gives · this election (since 2025)

Individuals 34% ($15,700.00)PACs & committees 63% ($29,450.00)Other organizations 3% ($1,500.00)

Shares are of the $46,650.00 that donors gave this election (since 2025). Of the $29,450.00 from PACs and committees, $26,450.00 is from PACs, $1,000.00 from other candidates' campaigns and $2,000.00 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 28% ($13,000.00)ZIP crosses the district line 1% ($550.00)Elsewhere in Iowa 68% ($31,500.00)Iowa, ZIP not mapped 1% ($500.00)Outside Iowa 2% ($1,100.00)

Between 28% and 29% of the $46,650.00 whose donor listed an address came from inside the district (Senate District 19) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

98% came from somewhere in Iowa and 2% from outside the state. $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.

Its filings report $49,226.00 raised in cash this election (since 2025), and $46,650.00 of that is listed donor-by-donor. The bars use the donor-by-donor part. Its newest report (filed 2026-07-20, $2,576.00 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 →

Between 12% and 35% of the $1,992.00 whose donor listed an address came from inside the district (Senate District 19) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

Not in the bars: $354.00 in donated goods and services this election (since 2025). The second bar also leaves out $40.00 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.

Zachary Mecham $51/day

$3,110.00 over 61 days · latest report

Barb Kniff McCulla $42/day

$2,576.00 over 61 days · latest report

Behind in total cash, Zachary Mecham is raising faster by the day right now — $51/day versus $42/day for Barb Kniff McCulla, 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.
