Cascadian states, especially Oregon and Washington, are US leaders in promoting voter turnout. They pioneered automatic voter registration and voting by mail, for example, and their voter turnout numbers are admirable. But Washington lags Oregon in one major way: many of its local elections have dismal turnout.

Take King County, Washington, which encompasses the heart of the greater Seattle area and is the most populous county in all of Cascadia, with 2.2 million residents. King County is, first of all, big. It’s got more residents than Idaho. It’s more than two Montanas or three Alaskas. Its county government, overseen by the elected County Executive, is also big, with a budget in the same range as these states. Its Elections Director oversees the largest election operations and ballot-counting center in the Northwest by a large margin. And King County Council members represent districts with far more residents than state legislators anywhere in Cascadia.

A trivial-sounding proposal to amend King County’s charter is the hidden blockbuster of next month’s county general election.

But King County’s voter turnout in elections for these posts is much lower than is turnout for state positions in any Cascadian states. Measured as a percentage of registered voters, it is often stuck in the 40s, while state positions across the region get turnout in the 60s or 70s. In fact, King County’s turnout is routinely 25 to 30 percentage points lower than turnout in Oregon for county elections. Oregonians are not more virtuous; their state just holds county elections at the same time as state and federal ones, in even years, when people have many more reasons to vote.

All of which explains why a trivial-sounding proposal to amend King County’s charter is actually the hidden blockbuster of next month’s county general election. By approving the measure, voters can move county elections from odd years to even years and, through this simple step, boost voter participation in county races by perhaps half or more. In short, they can move the election to when the voters are. By doing so, they can also engage an electorate that better represents the county—one that no longer overrepresents older voters, white voters, and homeowners. And they can inject fresh energy into a movement to win the same salutary rescheduling for city elections statewide, with similarly outsized benefits for representation.

Odd year out: We vote when the stakes are high

Chart showing how even year elections are more engaging than odd year electionsOver the last two decades, an average of 74 percent of registered King County voters cast ballots in even-year elections, voting in the mid-80s in presidential years and less in midterms, according to King County Elections data assembled by County Council staff. In odd years, only 47 percent typically voted. The high-stakes races in even years boosted turnout on average by more than 27 percentage points, an almost 60 percent increase. Lower-stakes odd-year elections draw less turnout. Off-season primary and special elections, when the stakes are lower still, sometimes only attract ballots from 20 percent of voters. (In Washington, state law allows as many as four elections a year, and five in presidential years, including slots for ballot questions such as school levies in February.)

“Nationwide, local voter turnout generally doubles when elections move from off-cycle to on-cycle contests.” –Zoltan L. Hajnal, PhD, elections scholar, UCSD

King County’s voting ratios are consistent with academic research on the subject. Writes Zoltan L. Hajnal of the University of California, San Diego, “Every one of the eight published studies on local election timing finds that moving to even year elections (often called on-cycle elections) is by far the biggest thing that localities can do to increase turnout. Nationwide, local voter turnout generally doubles when elections move from off-cycle to on-cycle contests.” That’s a remarkable finding, considering that get-out-the-vote and registration drives are lucky to boost participation by a percentage point or two.

Even-year elections engage more-representative electorates

In Seattle, which has one-third of King County’s population, odd-year voter turnout dips, especially for voters of color and young voters. That is, Seattle’s odd-year electorate is much older and whiter than the population. Consequently, it overrepresents homeowners and high-income households.

The same pattern is evident across Washington: since 2000, only 18 percent of voters under the age of 25 participated in odd-year local elections. They made up just 3 percent of the electorate—one-quarter their share of the voting-age population. In even-year elections, their turnout rate almost tripled to 50 percent.

The pattern holds across the United States, according to Hajnal: “[O]lder voters (those aged 65 or older) tend to dominate odd year contests. In odd year elections around the country, working class Americans, racial and ethnic minorities, and other disadvantaged groups are . . . underrepresented.”

Writing elsewhere with Vladimir Kogan of Ohio State University and Agustin Markarian of University of California, San Diego, Hajnal notes, “Whites . . . are almost twice as likely as Latinos and Asian Americans to participate in local contests. The imbalance by education, income, and age is just as stark.”

Skewing the electorate has consequences for democracy. A national study found that localities with high-turnout elections elected far more city councilors of color than did localities with low-turnout elections. Researchers Michael Harney and Sam Hayes compared school board members’ views with their constituents’ and found that school boards elected in even years matched public sentiments better than did boards elected in odd years.

Sure, more people will vote, but will they vote for local offices?

One objection to even-year elections is the claim that long ballots are overwhelming. Voters may mark their choices for president and governor but leave blank the local races at the bottom of the ballot.

It’s a reasonable concern, but it’s mistaken. The differences in voting that long ballots cause to races at the bottom of ballot, called “down-ballot drop-off,” are small compared with the massive increases in voting brought by even-year elections, as two examples illustrate.

  • In 2019, my then-colleague Kristin Eberhard compared contested, odd-year county races in Washington with contested, even-year county races in Oregon and Washington. She found that participation averaged 60 percent in the local even-year contests (buried at the bottom of long ballots) and 33 percent in the odd-year ones (prominent at the top of short ballots). (See figure below; data here.)

Chart showing how local elections also show even year elections have better turnout than odd year elections

  • King County does run elections for judges and prosecutor in even years, and these races routinely draw more voters than do elections for county executive and county councilors in odd years, even though the latter positions are more influential than the former. Indeed, in November 2020, 85 percent of county voters filled in their ballots on seven county charter amendments, answering Yes or No to uninspiring, far-down-the-ballots questions such as whether the county executive should have responsibility for bargaining over working conditions with employees of the county’s public safety department. The following year, only 43 percent of voters cast ballots for county executive, the top job in the county and the person who oversees a budget of almost $8 billion a year.

Down-ballot drop-off is not an issue, but odd-year elections are.

Consolidate elections in even years

Oregon, Idaho, Montana, and 36 of 39 Washington counties hold county elections in even years. All of them benefit from much higher turnout.

Shifting elections to even years would be just as good for other localities as for King County. Already, Oregon, Idaho, Montana, and 36 of 39 Washington counties hold county elections in even years. All of them benefit from much higher turnout.

The weak spots in Cascadian turnout are at the county and city levels of government. At the county level, three Washington counties—King, Snohomish, and Whatcom—vote in odd years, and Alaska’s alternative to counties, which are called “boroughs,” vote at unusual, off-cycle times, such as October of even years. At the city level, not only Washington but also Idaho and Montana run elections in odd years, and Alaska runs them in unusual, off-cycle times too. Odd-year, off-cycle city elections suppress turnout, just as odd-cycle county elections do. In Washington cities, for example, turnout mirrors the dismal rates in King County: 46 percent participation in odd years since 2000 and 73 percent in even years.

A century ago, the Progressive movement, intent on breaking American cities’ “political machines,” succeeded in disconnecting local elections from state and national ones by shunting them to odd years. Along the way, they also unintentionally boosted the local power of older, whiter, richer, homeowning, native-born citizens. The system stuck, and to this day almost 80 percent of US municipalities hold their elections in odd years or otherwise off-cycle.

But change is afoot.

  • Sightline’s Fall Fund Drive is happening now! Give to Sightline today and support smart policy solutions for a sustainable future.

  • Oregon has long since consolidated its county and city elections in even years, in sync with state and federal elections in November, lifting turnout.

    In 2015, California adopted a law to move elections to November of even years in every locality where turnout in off-cycle elections lagged 25 percentage points or more behind on-cycle elections. In the months that followed, some 54 cities across the state revised their codes and phased in the new schedule. That’s 11 percent of the state’s cities. In these cities, turnout has tripled, on average, as a result. In 2020, unfortunately, a California state court exempted from the law all the cities—generally the large ones—that have their own home-rule charters. Such charter cities make up a quarter, or 121, of the state’s 482 cities.

    Separately, though, some California charter cities are switching anyway. Los Angeles shifted to even-year elections in 2015. Angelenos adopted the calendar change at the ballot with a 72 percent “yes” vote, and other California home-rule charter cities have done the same by similarly lopsided margins: 83 percent in Glendale in 2018, for example, and 81 percent in Burbank and San Mateo. San Francisco voters will decide next month whether to join the trend and move to the evens.

    In 2018, Arizona approved a similar law, and in 2019, Nevada followed suit. Both explicitly included cities with home-rule charters. Meanwhile over the years, a steady stream of US localities flipped to even on their own, including Austin and El Paso, Texas; Sarasota and many other Florida cities; Trenton and other New Jersey cities; Baltimore, Maryland; Raleigh, North Carolina; and Santa Fe, New Mexico.

    In the 2022 Washington legislative session, Rep. Mia Gregerson (D–SeaTac) and nine colleagues co-sponsored a bill to move city elections off of the odd years. Outdoing the ambition of other states’ laws, the measure does not fiddle with thresholds of low turnouts to trigger a change. It simply eliminates odd-year elections entirely. It strikes them from the menu of options available in the state to all levels of government. Not only would off-cycle city and county elections disappear, so would ballot initiatives in low-turnout years.

    Such a dramatic simplification of the state’s election code would lift voter participation and improve representation in local elections statewide. It would catch Washington up with Oregon as a leader in voter turnout, and it would leapfrog the Evergreen State beyond California.

    But before the legislature in Olympia reconvenes in early 2023 and again takes up the Gregerson bill, King County voters—who are almost 30 percent of voters in the state—can show the legislature what to do by approving the hidden blockbuster on the November ballot, charter amendment 1. It’s a deceptively simple measure that promises to boost turnout by more than half, just by rescheduling county elections.
