In Washington , a vote-by-mail state , all ballots must be postmarked or dropped off by 8:00 p.m. at a designated ballot box or postmarked by the date of the primary . In the open primary , candidates must meet a threshold of 15 percent at the congressional district or statewide level in order to be considered viable . The 107 pledged delegates to the 2020 Democratic National Convention will be allocated proportionally on the basis of the results of the primary . Of the 107 pledged delegates , between 3 and 11 are allocated to each of the state 's 10 congressional districts and another 12 are allocated to party leaders and elected officials ( PLEO delegates ) , in addition to 19 at-large pledged delegates . Bonus delegates will be allocated as Washington shares a primary date with numerous other states holding contests the week after Super Tuesday ; these numbers do not yet account for these delegates
