Who gives · this election (since 2025)

Individuals 68% ($6,280.00)PACs & committees 32% ($3,000.00)

Shares are of the $9,280.00 that donors gave this election (since 2025).

Where they live · this election (since 2025)

In the district 34% ($3,115.00)ZIP crosses the district line 22% ($2,000.00)Elsewhere in Iowa 44% ($4,085.00)

Between 34% and 56% of the $9,200.00 whose donor listed an address came from inside the district (House District 84) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

100% came from somewhere in Iowa and 0% from outside the state.

The second bar also leaves out $190.00 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.

Polly Denison $10/day

$637.50 over 61 days · latest report

Thomas Gerhold $0.0/day

$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.
