Between 31% and 61% of the $6,659.67 whose donor listed an address came from inside the district (House District 15) this election (since 2025). It's a range because donor addresses are placed by ZIP code, and some ZIP codes cross the district line.

92% came from somewhere in Iowa and 8% from outside the state.

Blake Johnson · No Party

No donor-by-donor detail on file yet for this election in the state's itemized feed (the publisher dates the feed 2026-07-14, posted 2026-09-05).

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.

Marilyn J Mentzer $82/day

$5,000.00 over 61 days · latest report

Benjamin Schauer $70/day

$4,279.00 over 61 days · latest report

Jason Sherer $42/day

$2,554.10 over 61 days · latest report

$0.00 over 61 days · latest report

Behind in total cash, Marilyn J Mentzer is raising faster by the day right now — $82/day versus $70/day for Benjamin Schauer, 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.
