Tuesday 24 May 2016: All 44 of Washington's delegates to the Republican National Convention are allocated to presidential contenders based on the results of the voting in today's Presidential Primary.

• Each of the state's 10 congressional districts is allocated 3 delegates.
• If a candidate receives a majority of the vote or only 1 candidate receives 20% of the vote, that candidate receives all 3 delegates.
• If there are 2 candidates who receive at least 20% of the primary vote, then the top vote getter will be allocated 2 delegates and the other candidate will be allocated 1 delegate.
• If no candidate receives at least 20% of the vote or more than 2 candidates receive at least 20% of the vote, then the top three vote getters each receive 1 delegate.
• 14 at-large delegates (10 base at-large delegates plus 1 bonus delegates plus 3 RNC delegates) are allocated proportionally based on the statewide vote. At-Large candidates must receive at least 20% of the total statewide vote in order to be allocated delegates.
• Allocation is in proportion to the total statewide vote NOT the total vote of those candidates receiving 20% or more of statewide vote.
• Compute the number of delegates allocated to each Presidential candidate: 14 delegates × candidate's vote ÷ total statewide vote. Round to the nearest whole number.
• If more than 14 delegates are allocated, subtract 1 delegate from the candidate or candidates furthest from the rounding threshold until 14 delegates have been allocated.
• If fewer than 14 delegates are allocated (due to the 20% threshold or rounding), those delegates become unbound.
