Tuesday 26 April 2016 (presumably): 95 of 120 delegates to the Democratic National Convention are allocated to presidential contenders based on the results of the voting in today's Maryland Presidential Primary. A mandatory 15 percent threshold is required in order for a presidential contender to be allocated National Convention delegates at either the congressional district or statewide level. How the Democratic Proportional Delegate Allocation Math works.

• 64 district delegates are to be allocated proportionally to presidential contenders based on the primary results in each of the State's 8 congressional districts. District-level delegates are elected by a two-part primary in which delegate positions are allocated based on a Presidential preference primary and filled through the election of delegates on the ballot. National Convention delegates are selected from the highest vote getters.
• In addition, 31 delegates are to be allocated to presidential contenders based on the primary vote statewide.
  • 21 at-large National Convention delegates
  • 10 Pledged PLEOs
