Vice President Joe Biden and Vermont Sen. Bernie Sanders are running against each other to face off against President Trump in November.
In most cases, state Democratic parties award delegates to candidates based on their performance in a primary or caucus vote.
NPR and the Associated Press are keeping track of who has the most delegates throughout the primary season. At the Democratic National Convention in July, those delegates will choose a nominee for the party.
Not every presidential candidate who has run this year received delegates. Only those who have earned at least one delegate in any contest are listed on this page.
Delegate numbers shown are maintained by the Associated Press and are provided via an automatic feed. Because some counts are unofficial, numbers shown here may differ from what is reported elsewhere.
