Catelin Drey · Democrat
Who gives · this election (since 2025)
Individuals 87% ($218,424.93)PACs & committees 13% ($34,058.00)
Shares are of the $252,482.93 that donors gave this election (since 2025). Of the $34,058.00 from PACs and committees, $2,800.00 is from PACs, $258.00 from party committees and $31,000.00 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 14% ($35,012.53)ZIP crosses the district line 3% ($7,385.84)Elsewhere in Iowa 9% ($23,700.67)Iowa, ZIP not mapped 1% ($3,420.00)Outside Iowa 72% ($182,736.80)
Between 14% and 17% of the $252,255.84 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.
28% came from somewhere in Iowa and 72% from outside the state. $3,420.00 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 $294,684.39 raised in cash this election (since 2025), and $252,482.93 of that is listed donor-by-donor. The bars use the donor-by-donor part. Its newest report (filed 2026-07-20, $42,201.46 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: $120,363.56 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 $227.09 from donors with no usable address on the filing.

Not in the bars: $214,445.75 in donated goods and services this election (since 2025). The second bar also leaves out $95.00 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.
$42,201.46 over 61 days · latest report
$0.00 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.
