Washington has 40 delegates.

• 3 party leaders, the National Committeeman, the National Committeewoman, and the chairman of the Washington's Republican Party, will attend the convention as unpledged delegates by virtue of their position.
• 37 (27 district and 10 at-large) delegates are elected by the Primary and the Caucuses.
• 51% (37 × 0.51 = 18.87, round to 19) of these delegates are elected by Primary.
• 49% (37 × 0.49 = 18.13, round to 18) of these delegates are elected by Caucus.

Saturday 9 February 2008: Precinct Caucuses.

The Caucuses initiate the process of electing 18 (49% of 37) of the National Convention delegates. These delegates will attend the Republican National Convention officially "Unpledged".

Tuesday 19 February 2008: Primary.

19 (1 from each of the 9 Congressional Districts and 10 at-large) of Washington's delegates to the Republican National Convention are allocated to presidential contenders based on the results of voting in today's Washington Presidential Primary. Voters are required to sign a form stating they are Republicans (as voters do not have to declare political party membership to vote in the state's regular primaries or general elections).

• 9 district delegates are to be allocated to presidential contenders based on the primary results in each of the 9 congressional districts: each congressional district is assigned 1 National Convention delegate and the presidential contender receiving the greatest number of votes in that district will receive that district's National Convention delegate.
• 10 delegates are to be allocated proportionally to presidential contenders based on the primary vote statewide. A 20 percent threshold is required in order for a presidential contender to be allocated National Convention delegates at the statewide level.

Saturday 22 March - Saturday 3 May 2008 (tentative date): Republican Party County Conventions convene in each county. Each County Convention chooses delegates to both the Congressional District Conventions and the State Convention.

• County Conventions choose both the county's delegates to the Republican Party Convention of the Congressional District the county is a part of as well as the county's delegates to the Washington State Republican Convention. Again, there is no formal system applied in the County Convention to relate the presidential preference of the County Convention delegates to the choice of the county's delegates to either the Republican Convention of the Congressional District in which the county is located or the Washington State Republican Convention; each County Convention alone determine if presidential preference is to be a factor and, if so, how it is to be applied.
• Once more, there is no formal system governing how the District Convention is to go about indicating its presidential preference to the State Convention. It is the delegates in attendance at the Congressional District Convention alone who decide how best to go about this.

Friday 30 May - Saturday 31 May 2008: The State Convention convenes.

There is no formal system applied in the State Convention to relate the presidential preference of the Caucus participants to the choice of the National Convention delegates. The participants at the State Convention alone determine if presidential preference is to be a factor in such choice and, if so, how it is to be applied.

• The State convention elects 18 delegates. These delegates will attend the Republican National Convention officially "Unpledged".
• 3 party leaders, the National Committeeman, the National Committeewoman, and the chairman of the Washington's Republican Party, will attend the convention as unpledged delegates by virtue of their position.
