The Alternative Presidential Preference Poll may only be used when there is an incumbent Republican President ...." [Chapter 2, Section 13 - Standing Rules of the Nevada Republican Central Committee]. The meeting is held in Pahrump, Nevada.

Alternative Presidential Preference Poll (preliminary)
Included in Nationwide vote.

• All 25 National Convention delegates are proportionally bound to Presidential contenders based on today's Alternative Presidential Preference Poll vote.
• A 3.33% threshold is required in order for a contender to be allocated delegates [1 ÷ 30 delegates = 3.33%].
• Chapter 3, 1.0 says "National Delegates ... shall be allocated proportionally based on the ... results ... rounded to the nearest whole number" while Subsection 8.1 says "When rounding off numbers in the calculation of the allocation of Delegates, the calculation will be based on the largest remainder method". Standing Rules 1.0 and 8.1 appear to be contradictory.
  Interpretation A (round to the nearest whole number):
  For those candidates receiving 3.33% or more of the vote: The number of delegates = 25 × (candidate's popular vote) ÷ (total statewide vote for those candidates exceeding the threshold) rounded to the nearest whole number. Not sure what to do if rounding allocates too few or too many delegates.
  Interpretation B (largest remainder method):
  For those candidates receiving 3.33% or more of the vote: The number of delegates = 25 × (candidate's popular vote) ÷ (total statewide vote for those candidates exceeding the threshold). Award each candidate the whole number of delegates. Beginning with the candidate with the largest remainder, round up to the next whole number. Repeat for the next highest remainder until all delegates are allocated.
