Washington held its top-two primary on August 4. In the only U.S. race with no incumbent, the Tenth District, two Democrats placed first and second, so they will be the only candidates on the November 3 ballot. Eight Republicans ran. Together they polled 41.3% of the vote, but because there were so many of them, they split up the Republican vote. The Tenth District includes the southern half of Tacoma, as well as the state capitol, Olympia.

In the other U.S. House races in Washington, there will be one Democrat and one Republican on the November ballot. Libertarians ran in three different districts, but they did not qualify for the November ballot. No other minor parties had any candidates. There were a few independents with labels, such as “Congress Sucks” and “Essential Workers” but none of them got more than 1%.
