King County Elections' ballot drop box at Issaquah City Hall, 130 E. Sunset Way, is open until 8 p.m. May 24, 2016, for the state's presidential primary.
Unlike all other Washington elections, presidential primary voters are required by law to declare a party for the primary they're voting in. The declarations, written by the Democratic and Republican parties, are located on the return envelope. Without a signature and checking the appropriate party box, the vote will not be counted.
Voters will receive a unified ballot with both party primary lists, but voters can only choose a candidate within the party they declared.
The parties will receive a list of voters who chose their ballot.
Republicans will use the primary results to allocate their national convention delegates; Democrats will not. Democrats will use their March 26 caucuses and subsequent conventions/caucuses to allocate national convention delegates.
More information about the presidential primary is available from the Secretary of State's Office.
