The March Presidential Primary includes the Democrat and Republican candidates for President.

Each major political party decided which candidates would be printed on their side of the ballot. Once each party submitted their list on January 7 to the Secretary of State, changes could not be made. (RCW 29A.56) It's possible for candidates to suspend their campaigns before March 10, but every voted ballot returned to the local elections office will be processed and all results reported.
