Less than one hundred hours from now, on Tuesday, August 17th, Washington State’s August 2021 Top Two election will be certified and the results of the qualifying round of this year’s local elections cycle will become final.
With no ballots listed by King County Elections as awaiting tabulation, and with almost a month having now passed since we announced the electoral findings from our July 2021 survey of the Seattle electorate, it seems like a good time to revisit our poll findings and examine to what extent they anticipated the outcomes in the actual returns tallied by King County Elections.
Our survey, conducted by Change Research from July 12th-15th, 2021, ended up being the only independent poll with publicly released results during the lead-up to August 3rd, the deadline to return ballots in the election. While Elway Research did conduct a poll on behalf of Crosscut during that timeframe, it was a statewide poll, not a city poll, and so respondents were not asked about Seattle races.
At the time we were drawing up our 2021 research plans, our team discussed the possibility that there might end up being a total dearth of independent electoral polling in Seattle this year, especially in the Top Two phase.
We agreed that NPI would step up to ensure that scenario wouldn’t happen.
Choosing to expand our research polling to the local level — building on the statewide polling that we’ve been doing for over half a decade — has been one of the best decisions that our organization has ever made. I am grateful to our staff, our board, and our supporters for putting us in a position to answer the call.
As I wrote last month, our region sorely needs more credible, independent public opinion research. NPI is stepping up to meet the need. Reliable data is a very useful resource to have in an era of rampant misinformation and disinformation.
While no poll can predict the future, trustworthy polling can provide a valid snapshot of what the electoral landscape looks like ahead of an upcoming election, and suggest what voters might collectively decide in that election.
After results roll in, having trustworthy polling to refer back to gives political observers more context to work with when trying to interpret the data and draw conclusions about what happened and why it happened.
We are now at such a post-election juncture. So let’s dive in and see how the results line up with our polling from last month!
Mayor of Seattle
What the poll found: Of the fifteen candidate field, the poll indicated that Bruce Harrell and Lorena González were the frontrunners, with 32% (a plurality) undecided. Harrell placed first in the poll and González second, with Colleen Echohawk, Jessyn Farrell, and Andrew Grant Houston trailing them.

What happened in the election: Voters have selected Bruce Harrell and Lorena González as the Top Two candidates. On Election Night, Harrell had a ten point lead over González, a larger margin than what he enjoyed in our polling. But in late ballots, his lead shrunk and González’s share of the vote grew. The two candidates are now only two points apart, which suggests an extremely competitive runoff for Mayor in the general election this autumn.
Current results (final results available after August 17th):
 | Bruce Harrell 69,554 votes | 34.02% |
 | M Lorena González 65,627 votes | 32.1% |
 | Colleen Echohawk 20,994 votes | 10.27% |
 | Jessyn Farrell 14,905 votes | 7.29% |
 | Arthur K Langlie 11,362 votes | 5.56% |
 | Casey Sixkiller 6,904 votes | 3.38% |
 | Andrew Grant Houston 5,473 votes | 2.68% |
 | James Donaldson 3,212 votes | 1.57% |
 | Lance Randall 2,800 votes | 1.37% |
 | Clinton Bliss 1,615 votes | 0.79% |
 | Omari Tahir-Garrett 390 votes | 0.19% |
 | Bobby Tucker 374 votes | 0.18% |
 | Henry C Dennison 346 votes | 0.17% |
 | Stan Lippmann 322 votes | 0.16% |
 | Don L Rivers 189 votes | 0.09% |
Analysis: When it came time to make a decision, most voters who were undecided went with one of the frontrunners. That’s why both Harrell and Gonzalez are so far out in front of the rest of the pack.
The poll indicated Harrell had the best chance of getting through due to having already garnered a strong base of support and suggested Gonzalez was the most likely candidate to get the other spot. That’s precisely what happened.
At the time the poll returned from the field, Colleen Echohawk was right behind Gonzalez, at 10%. Interestingly, that’s the exact same percentage she’s getting in the actual election… 10.27%! In retrospect, it looks like Echohawk peaked around or sometime not long before our poll was in the field. She certainly had a chance to connect with undecided voters, but they ended up with the frontrunners.
Jessyn Farrell and Andrew Grant Houston were the other candidates in the top tier, tied for fourth at 6%, respectively. Farrell did a little bit better in the election, garnering 7.29%, while Grant Houston did worse, pulling in 2.68%.
City Attorney
What the poll found: Perhaps no result from our survey turned more heads than our finding for Seattle City Attorney. Our research indicated that it was a three-way race between incumbent Pete Holmes and his two challengers, with Holmes barely ahead and in grave danger of being overtaken by both of them. Holmes received 16% support in the survey, while challengers Nicole Thomas-Kennedy and Ann Davison each received 14%.
A majority of respondents, 53%, said they were undecided, but the low number for Holmes, a three-term incumbent, indicated he was in big trouble.

A visual of NPI’s poll finding for Seattle City Attorney, 2021
What happened in the election: Seattle voters ended Pete Holmes’ bid for a fourth term by selecting Thomas-Kennedy and Davison as the top two candidates for the position. Each candidate landed in the thirties in the actual election, vindicating our characterization of it being a three-way race. In the initial returns on Election Night, Davison had the top spot, with Holmes in second and Thomas-Kennedy in third. By Thursday afternoon, close to forty-eight hours after Election Night, Holmes traded places with Thomas-Kennedy, while Davison remained in first place. By Friday afternoon, Thomas-Kennedy had surged into the top spot, ahead of Davison, with Holmes still out of contention in third.
Current results (final results available after August 17th):
 | Nicole Thomas-Kennedy 71,234 votes | 36.37% |
 | Ann Davison 64,101 votes | 32.73% |
 | Pete Holmes 60,009 votes | 30.64% |
Analysis: As I wrote last week, voters are known for punishing complacency when least expected to. Pete Holmes was overwhelmingly reelected four years ago with three-fourths of the vote against challenger Scott Lindsay, but this cycle, he couldn’t even manage to garner half as much support against two opponents.
Prior to the release of our poll finding, Holmes’ campaign had been in what you might call cruise control mode, having seemingly not considered the possibility of the candidate failing to advance to the general election. After the publication of our finding, Holmes began campaigning more vigorously, offering critiques of his opponents. But voters dissatisfied with his performance backed them anyway, leaving him in the same boat Greg Nickels found himself in twelve years ago.
City Council, Position #8 (At-Large)
What the poll found: Our research suggested that incumbent Councilmember Teresa Mosqueda was on track for reelection against a large field of ten challengers. In the survey, Mosqueda received 26%, with all of her challengers down in the single digits, or at zero. Of the challengers, the poll indicated that Kate Martin could have the best chance of ending up in the general election along with Mosqueda; Martin received 6%, with no other challenger polling above 2%. A majority of respondents, 55%, said they were undecided.

A visual of NPI’s poll finding for Seattle City Council Position #8, 2021
What happened in the election: Although a huge number of voters professed themselves to be undecided — in fact, more than in any of the other three races! — most of them eventually decided to back Mosqueda’s reelection.
She currently has 59.36% of the vote, more than any other candidate running for citywide office in Seattle this year. However, Mosqueda’s opponent in the general election won’t be Kate Martin. In the biggest surprise of the Top Two, bridge engineer Kenneth (Ken) Wilson came out of nowhere to grab the second place spot, despite having spent almost no money and having been ignored by the mass media. Wilson currently has 16.21% of the vote, with Martin in third at 11.56%.
Current results (final results available after August 17th):
 | Teresa Mosqueda 112,858 votes | 59.36% |
 | Kenneth Wilson 30,825 votes | 16.21% |
 | Kate Martin 21,969 votes | 11.56% |
 | Paul Felipe Glumaz 10,214 votes | 5.37% |
 | Alexander White 2,468 votes | 1.3% |
 | Bobby Lindsey Miller 2,433 votes | 1.28% |
 | Jesse James 2,049 votes | 1.08% |
 | Jordan Elizabeth Fisher 1,805 votes | 0.95% |
 | George Freeman 1,575 votes | 0.83% |
 | Alex Tsimerman 960 votes | 0.5% |
 | Brian Fahey 884 votes | 0.46% |
Analysis: This was the only race in which our poll did not detect that one of the top two finishers was even in contention. The survey anticipated Mosqueda might finish in first place (and she has), but it didn’t register any significant degree of support for Kenneth Wilson. We think there’s a simple reason for that: Kenneth Wilson’s remarkable surge occurred after the poll had fielded in mid-July.
Wilson probably benefited from the negative perceptions that a lot of people in Seattle anecdotally seem to have of activist Kate Martin, whose “Park My Viaduct” ballot measure proposal fell utterly flat with voters four years ago.
Although Martin is outperforming her standing in the survey, Wilson was able to eclipse her by offering voters who wanted an alternative to Teresa Mosqueda a candidate they could feel good about supporting. Martin, metaphorically speaking, has spent years burning bridges with people across Seattle, while Wilson, literally speaking, has spent years helping to get bridges built in and beyond the city.
As mentioned, Wilson was in a position to capitalize on voters’ interest in functioning bridges because he is a bridge engineer. He ran on getting the high West Seattle Bridge reopened to at least one lane of traffic in each direction, emphasizing it on his website and in his voter’s pamphlet statement. That message clearly resonated with a significant number of voters.
Aside from The Cascadia Advocate and Seattle Times columnist Danny Westneat, who took the time to talk to the candidate, Wilson’s surge has not gotten much attention from the press. But perhaps that will soon change. And maybe now that Wilson has gotten through the elimination round, he’ll make fundraising a priority so he can afford to make his campaign more visible to voters.
City Council Position #9 (At-Large)
What the poll found: In the contest for the city’s other at-large council position, which is an open seat this year, our survey found that activist Nikkita Oliver and small business owner Sara Nelson were the leading candidates. Oliver received 26% support in the survey, while Nelson received 11%. Brianna Thomas, the chief of staff to Lorena Gonzalez, placed third in the survey with 6%.
Half of respondents surveyed, 50%, said they were undecided.

What happened in the election: Oliver placed first, Nelson placed second, and Thomas placed third — the same order as in the poll. Each candidate garnered more support than in the survey, indicating that they all got additional support from undecided voters. Nelson did by far the best job of reeling in undecided voters to her side, surging from just 11% in the survey to 39.49% in the actual election… a huge gain. Oliver went from 26% in the survey to 40.16% in the election, surpassing Nelson in late ballots (Nelson held the first place spot on Election Night). Thomas went from 6% in the survey to 13.42% in the election.
Current results (final results available after August 17th):
 | Nikkita Oliver 79,643 votes | 40.16% |
 | Sara Nelson 78,304 votes | 39.49% |
 | Brianna K Thomas 26,617 votes | 13.42% |
 | Corey Eichner 7,019 votes | 3.54% |
 | Lindsay McHaffie 3,042 votes | 1.53% |
 | Rebecca L Williamson 1,645 votes | 0.83% |
 | Xtian Gunther 1,403 votes | 0.71% |
Analysis: Nikkita Oliver was able to build on their already strong base of support to earn the top spot in the general election, while Sara Nelson’s campaign took off and soared in the days leading up to August 3rd. Combined, Oliver and Nelson have about eighty percent of the vote overall. They are less than 1,500 votes apart. This race could be incredibly competitive in the November general election.
On the morning after Election Night, one Internet commenter argued to NPI that our survey must have been flawed because it did not predict Nelson’s strong performance. At the time, Nelson was ahead of Oliver, and this commenter theorized that the results didn’t line up because our sample was unrepresentative.
But as we pointed out to them, their reasoning didn’t make any sense. As I explained in the introduction to this post, polls can’t predict what will happen, they can only suggest what might happen. That is an important distinction.
If our sample had been unrepresentative, then the results of the whole survey would have been off, and we would not be seeing the correlations we’re seeing between our findings and the unofficial results so far across the different races.
As with Kenneth Wilson, the plausible explanation for why Sara Nelson is doing so much better in the actual election than in our poll is because her candidacy caught fire and resonated with voters during the homestretch. Because our poll was in the field before ballots dropped, this wasn’t something it could detect. Nevertheless, it did suggest that Oliver might come in first and Nelson second, which is what happened, despite the large number of undecided voters.
Final thoughts
About three weeks went by in between when our survey returned from the field and when the first results from the tabulation of ballots cast by voters became available. Although pluralities and majorities of respondents to our survey said they were not sure who they were voting for, it was evident that some candidates were in a much stronger position heading into the voting than others.
On August 3rd, we got our first results. While that fresh data was nice to have, it was also somewhat incomplete. KCE data showed that most of the ballots cast in Seattle were returned in the final hours of the election, with a majority of on-time ballots having been sent back in the final twenty-four hours. That meant there was a possibility of serious movement and some lead changes in the late ballots.
And indeed, that’s what we saw. We now have more complete results to pore over, and that data shows that our survey succeeded in yielding credible insights about Seattle’s electoral landscape ahead of the Top Two election.
This success builds on our track record at the statewide level.
In last year’s presidential election, we were the only organization to publicly poll up and down the entire statewide ballot, asking voters who they were supporting in each of the candidate elections for statewide executive positions and State Supreme Court, as well as for Referendum 90, concerning sex ed. In each contest, the results lined up with what our poll found, as explained here.
Prior to that, our polling for United States Senate in 2018 had been on the money, anticipating Democratic incumbent Maria Cantwell’s eventual margin of victory over Republican challenger Susan Hutchison months in advance.
We are delighted to have been able to work with Change Research on this project. Change, which just celebrated its fourth anniversary, is a firm that shares our values and commitment to conducting rigorous research.
Change did a great job with their modeling of the electorate for this project, ensuring that the neutral questions that our team at NPI had written would be asked of a representative sample. Those are the two most important keys to good polling, by the way: neutral questions asked of a representative sample.
Survey methodology
- Change Research, a Public Benefit Corporation based in California, surveyed 617 likely August 2021 Top Two election voters in Seattle from Monday, July 12th to Thursday, July 15th on behalf of the Northwest Progressive Institute. All respondents participated online.
- Change used targeted advertisements on Facebook, targeted advertisements on Instagram, and text messages sent via the echo19 and/or Scale To Win platforms to cell phone numbers listed on the voter file for individuals who qualified for the survey’s sample universe, based on their voter file data.
- Regardless of which of these sources a respondent came from, they were directed to a survey hosted on SurveyMonkey’s website. Ads placed on social media targeted all adults living in Seattle. Those who indicated that they were not registered to vote were terminated.
- As the survey fielded, Change used dynamic online sampling: adjusting ad budgets, lowering budgets for ads targeting groups that were overrepresented and raising budgets for ads targeting groups that were underrepresented, so that the final sample was roughly representative of the population across different groups.
- The survey was conducted in English, and has a modeled margin of error of 4.3% at the 95% confidence interval.
We’ll be back for the general election!
NPI and Change Research will be joining forces again this autumn to survey Seattle voters in advance of the November 2020 general election. We look forward to bringing you more credible insights about what’s happening in the Emerald City before voters make their final decisions this autumn.

The August Top Two results are (mostly) in. How do they line up with our Seattle polling?
Less than one hundred hours from now, on Tuesday, August 17th, Washington State’s August 2021 Top Two election will be certified and the results of the qualifying round of this year’s local elections cycle will become final.
With no ballots listed by King County Elections as awaiting tabulation, and with almost a month having now passed since we announced the electoral findings from our July 2021 survey of the Seattle electorate, it seems like a good time to revisit our poll findings and examine to what extent they anticipated the outcomes in the actual returns tallied by King County Elections.
