Democratic Delegate Allocation Math
The Democrats use a single formula for proportional allocation. That is, it is used for the allocation of the the District, PLEO, and At-Large delegates in every jurisdiction.
The number of delegate positions allocated to each presidential candidate (including uncommitted) is determined as follows:
Step 1: Tabulate the percentage of the vote that each preference receives.
Step 2: Re-tabulate the percentage of the vote, to three decimals, received by each presidential preference excluding the votes of presidential preferences whose percentages in step 1 fall below 15%. Fine point: If no Presidential preference reaches a 15% threshold, the threshold is the half the percentage of the vote received by the front-runner [Delegate Selection Rules for the 2024 Democratic National Convention - Rule 14.F.]. The total vote is called the qualified vote.
Step 3: Multiply the number of delegates to be allocated by the percentage received by each presidential preference in step 2. In this example there are 5 delegates.
Step 4: Delegates are allocated to each presidential preference based on the whole numbers that result from the multiplication in Step 3.
Step 5: The remaining delegates, if any, are awarded in order of the highest fractional remainders in Step 3.
This is represented as:
Fine point: If a Presidential candidate is no longer a candidate at the time of selection of the PLEO and At-Large delegates, then those at-large slots that would have been allocated to the candidate will be proportionally divided among the remaining preferences entitled to an allocation. In other words, candidates who drop out before the selection time (often at the State Convention) remain eligible to receive District Delegates but any statewide Delegates won will be reallocated. The selection time is when the individual, who will attend the National Convention, is selected to fill the delegate position.
