The District 4 money ceiling

Maja Viklands Harris reopened the 2024 District 4 race in Rose City Reform this week, reconstructing round by round how Eric Zimmerman took the third seat from Eli Arnold. Zimmerman started 118 first-choice votes behind Arnold, the two traded places across 31 rounds and sat 29 votes apart at the tightest point, and when Arnold was finally eliminated 6,459 of his ballots counted for Zimmerman.

Near the end she turns to 2026 and lists what incumbency now gives Olivia Clark, Mitch Green, and Zimmerman: "name recognition, a larger platform, and an established donor base." The first two are hard to measure from outside a campaign. The third one shows up in the filings.

Portland's Small Donor Elections program matches small contributions to participating candidates ten to one, which makes it the largest single source of money for most of this field by a wide margin. So the question the filings can answer is not who raised the most. It is who has unlocked the most public money, and what is stopping the rest.

Net of the match, this field is nearly level

Strip out the public money and the private fundraising of the four returning players falls inside a $30,000 band: Clark $68,662, Green $61,748, Arnold $58,634, Zimmerman $39,264. Arnold, who holds no office and lost in 2024, is within $10,000 of the best-funded incumbent in the race.

Zimmerman is the weakest of the four on both counts. He won the seat in 2024, and he has since raised the least private money of the four by a clear margin and drawn the least public money by $32,020.

Most of the money in this race comes from the city, and the city releases it by donor count, not by dollars raised.

The match is tiered on people, not dollars. City Code 2.16.070 caps a council candidate at $100,000 once at least 250 matchable donors have given $5 or more, then adds another $100,000 for each further 500 new donors, to a maximum of $300,000. The city publishes the same rule as running totals: 250 donors for the first $100,000, 750 for $200,000, 1,250 for $300,000. A matchable donor is an individual 18 or older who lives in Portland, so money from outside the city does nothing to lift a candidate's cap.

Those are the statutory numbers, and for most of this cycle they were not the operative ones. The Elections Commission cut match caps by 65 percent in March 2025 because the program was underfunded, dropping the council's first tier to $35,000. Council money lifted it to $50,000 that August. The full $100,000 tier came back only on 24 June 2026, paid for with one-time funds, and the same notice warns that caps will have to be cut by roughly half again for 2028 unless the city appropriates ongoing money.

That history is written into the payment dates. Clark, Green, and Arnold each took $50,000 in January, when $50,000 was the ceiling, then each took a second $50,000 in June and July once the ceiling doubled. Zimmerman's entire $67,980 arrived in one payment on 23 July, an amount he could not have collected at all under the old cap.

Willamette Week reported in June that Clark had 666 donors, 84 short of the 750 that would open her second block, and that Arnold had earned $148,600 against a ceiling that was then $50,000 and is now $100,000.

Crossing a tier does not hand a candidate $100,000. It lifts the ceiling by that much, and what they can then collect is only what they have already earned. For Clark that is $30,330 waiting behind 84 donors. For Arnold it is $48,600, the largest unclaimed balance in the district, waiting behind a donor count the city has not published. Green is owed $10,913 on the same terms.

Clark's 666 is the only donor count the city has published for this field. Arnold and Green both stopped at exactly $100,000, which is what falling short of 750 donors looks like from the outside.

The last District 4 race was decided by 874 votes. Clark is 84 donors short of $30,330 she has already earned.

Arnold entered in November 2025 with the biggest single month any of them has posted outside of Green's July, and has raised steadily since. Green's $15,306 in July is the largest month in the race. Zimmerman's spring was his best stretch, and then he went quiet in July, the month before filing closes and the fall campaign begins.

Spending tells a different story from raising. Green has spent $71,613, more than twice anyone else in the field, and 44 percent of everything he has taken in. Clark has spent $17,925 and Zimmerman $8,015, holding roughly nine tenths and seven eighths of their money respectively. Whether that reads as discipline or as a slow start depends on what happens over the next two weeks: filing closes for incumbents on 18 August and for everyone else on 25 August.

Zimmerman took $4,363 from labor committees, about double Green's $2,125

Harris finds that the transfers which pushed Zimmerman past Arnold came from progressive voters rather than fellow moderates, roughly 2,600 of them against Arnold's 1,600, even though the two men drew on the same larger bloc. The money crosses the same way, and it is easier to measure.

Zimmerman is the largest recipient of organized labor money in the field, at $4,363. SMART Local 16, IBEW Local 48, Plumbers and Steamfitters, Portland Metro Fire Fighters, the Iron Workers district council, LIUNA Local 737, and the Northwest Oregon Labor Council have all given to the councilor most often described as a moderate. Green, who ran as a democratic socialist, has taken $2,125 from committees, chiefly the Portland Association of Teachers. Clark sits between them at $2,250, though hers is the least union-weighted of the three: $1,250 of it is labor money and the rest came from Betsy PAC and Kitzhaber for Governor.

Several of these organizations gave to more than one candidate. IBEW Local 48 and the Iron Workers each gave to Clark, Green, and Zimmerman. Jubitz Corporation gave to Clark and Zimmerman. One individual, Aidan Willis, gave $875 to Clark, Zimmerman, and Arnold on the same day, 26 November 2025. That $875 is above the city's published limit of $613, which note 4 takes up.

Arnold accepted no organizational money at all. His $58,634 is individuals and small aggregated contributions, which is also why he sits on the largest unclaimed match balance in the district.
