Tuesday 1 March 2016: 16 of 26 delegates to the Democratic National Convention are pledged to presidential contenders based on the results of the voting in today's Vermont Presidential Primary. A mandatory 15 percent threshold is required in order for a presidential contender to be pledged National Convention delegates at either the congressional district or statewide level. How the Democratic Proportional Delegate Allocation Math works.

• 11 district delegates are to be pledged proportionally to presidential contenders based on the statewide primary results as Vermont has only one Congressional District.
• In addition, 5 delegates are to be pledged to presidential contenders based on the primary vote statewide.
  • 3 at-large National Convention delegates
  • 2 Pledged PLEOs
