Three prominent candidates for mayor of Portland filed detailed campaign finance reports this week that provide a look inside what is expected to be a record-setting election.

Mayor Ethan Strimling, City Councilor Spencer Thibodeau and former school board member Kate Snyder raised a combined $207,000 as of June 30. Strimling has far outraised his challengers, accounting for $102,451 of the total raised.

Fair Elections Portland, a recently formed group that wants Portland to adopt a publicly financed clean elections system, said the fundraising totals four months before the Nov. 5 election indicate this race will far exceed the money raised in Portland’s two previous mayoral elections. The total raised by mayoral candidates in 2015 was a little more than $182,000. In 2011, 15 candidates raised a total of a little more than $300,000, the group said.

Fair Election Portland’s said the increased level of fundraising and spending underscores the need for public financing to replace private donations in Portland elections. “Local elections should be about people, not money,” Anna Kellar, spokeswoman for Fair Elections Portland, said in a written statement.

While the three candidates announced fundraising totals last week, the reports filed Monday provide the details about who donated and how the campaigns are spending the money. A fourth candidate, Thaddeus St. John, launched his campaign last week but did not file a report indicating any fundraising activity.

Candidates for mayor do not have to file nominating petitions until Aug. 26, so it’s not known how many candidates will be on the ballot in November.

Strimling has raised $102,451 since November, including $60,139 since the beginning of 2019. His campaign spent $31,459, leaving a cash balance of $70,237, according to the report.

Thibodeau has raised $59,410 since entering the race Jan. 9. His campaign has spent $26,340, leaving a cash balance of $33,070.

Snyder has raised $45,070 since she joined the race March 26. She has spent $15,835 and has $29,234 cash in hand, her report says.

The reports cover all fundraising and spending between Jan. 1 and June 30. The next round of reports will be due Sept. 24.

The maximum individual donation is $850, and some donations are $10 or less. Donors who give less than $50 in total are grouped together and not listed by name.

Strimling’s large donors include residents and business leaders, political allies, out-of-state supporters and labor unions.

According Strimling’s campaign finance report, 22 percent of his named contributions since Jan. 1 were from Portland individuals or businesses. Strimling’s in-state contributions, excluding Portland residents, accounted for 21 percent of his total contributions. Out-of-state contributions accounted for 31 percent of Strimling’s total contributions. Some of those are unions that likely represent local workers. The remaining 26 percent of  cash contributions were from unnamed donors who gave less than $50.

Among the unions supporting Strimling, the International Association of Machinists and Aerospace Workers donated $850, the International Brotherhood of Electrical Workers and International Brotherhood of Teamsters each donated $800 and the Portland Longshoreman’s Benevolent Society donated $500 and International Union of Elevator Constructors Local 4 each donated $500.

Thibodeau’s large donors include city residents, leaders of Portland’s business and legal communities and several prominent real estate developers and companies.

About 59 percent of the contributions were made by people identified as Portland residents or businesses, 34 percent came from other Maine donors and 6 percent were from out-of-state contributions. About 2 percent of his total contributions were donations of $50 or less.

Thibodeau’s spending includes $7,200 to Chann Creative for campaign consulting, and $4,000 for campaign videos, in addition to spending on web ads and printing campaign signs and literature.

Approximately 41 percent are Portland residents, 24 percent are Maine residents and 27 percent reside out of state. The rest were small, unnamed donors.
