Catelin Drey · Democrat

Who gives · this election (since 2025)

Individuals 57% ($317,231.24)PACs & committees 43% ($238,708.00)Other organizations <1% ($50.00)

Shares are of the $555,989.24 that donors gave this election (since 2025). Of the $238,708.00 from PACs and committees, $72,550.00 is from PACs, $258.00 from party committees and $165,900.00 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).

$98,337.31 of the individuals' money is from recent rows read from the Ethics Board's public search, which does not say whether a giver is a person or an organization. We count a giver there as an individual unless the state's older records list the same name as an organization or the name is plainly one (a PAC, party, committee, business, trust or union).

Where they live · this election (since 2025)

In the district 11% ($61,349.12)ZIP crosses the district line 3% ($15,927.49)Elsewhere in Iowa 21% ($117,189.93)Iowa, ZIP not mapped 2% ($9,195.00)Outside Iowa 63% ($351,631.61)

Between 11% and 14% of the $555,293.15 whose donor listed an address came from inside the district (Senate District 1) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

37% came from somewhere in Iowa and 63% from outside the state. $9,195.00 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.

$555,989.24 in cash this election (since 2025), listed donor-by-donor in the state's itemized records (the rows we hold reach 2026-10-20: the publisher's extract, dated 2026-07-14, plus the Ethics Board's public search, read 2026-10-19). · full record →

Not in the bars: $371,475.06 in donated goods and services this election (since 2025) and $2,000.00 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 $696.09 from donors with no usable address on the filing.

Individuals 35% ($33,023.18)PACs & committees 65% ($60,725.00)

Shares are of the $93,748.18 that donors gave this election (since 2025). Of the $60,725.00 from PACs and committees, $1,500.00 is from PACs and $59,225.00 from party committees.

$7,880.00 of the individuals' money is from recent rows read from the Ethics Board's public search, which does not say whether a giver is a person or an organization. We count a giver there as an individual unless the state's older records list the same name as an organization or the name is plainly one (a PAC, party, committee, business, trust or union).

Between 13% and 28% of the $93,653.18 whose donor listed an address came from inside the district (Senate District 1) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

$93,340.06 in 22 payments to 10 different recipients this election (since 2025), as this committee itemized them. Its filings report $93,340.06 spent since 2025 (newest report in our copy filed 2026-10-19). The two are the same to the cent.

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.

Biggest givers: the same cash rows, added up by the giver's name as filed (one giver filed under two spellings appears twice), refunds netted, a committee's receipts under its own code and its account interest left out; in-kind support and loans are not in the list. A linked giver is a state-registered committee; its page counts what it reported paying, since 2023, so its figure can differ from the one here. Givers without a link have no page on this site: people, and organizations that are not among the state-registered committees it tracks. Who each campaign paid: itemized payments since 2025-01-01, refunds netted, loan repayments left out, payees as each treasurer typed them, joined only by case, punctuation and legal form (Inc., LLC), so one vendor typed two ways can appear twice. Basis: itemized records, which list each gift and payment, not the totals reported on filings. Source: Iowa Ethics & Campaign Disclosure Board contributions and expenditures (the rows we hold reach 2026-10-20: the publisher's extract, dated 2026-07-14, plus the Ethics Board's public search, read 2026-10-19; payments in our copy downloaded 2026-10-24).

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.

Catelin Drey $2,840/day

$261,304.85 over 92 days · latest report

Christopher Prosch $735/day

$67,605.00 over 92 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, and the rate can't tell them apart; a committee's donation page breaks its money down by gift size.
