evidence: Washington sent out ballots for its Aug. 6 statewide primary election, which does not include a presidential primary. It held its presidential primary earlier this year, on March 12. President Joe Biden won Washington’s Democratic presidential primary in March, according to the certified election results. Biden has since dropped out of the race and endorsed Vice President Kamala Harris. Under Washington law, presidential candidates must be certified for the November ballot by Aug. 20, which falls before the Democratic nominee could be formally elected at the Democratic National Convention. Washington’s secretary of state will accept a letter from the Democratic National Committee attesting to the party’s alternate nominee, a spokesperson said.
