The delegate tracker
Winning delegates, the people who endorse a candidate at the party conventions in July, is key to securing the nomination.
The Democratic totals include the delegates won per state, as well as so-called "unpledged" or "super delegates". Hillary Clinton has a huge lead among the party leaders and elected officials who each get a vote at the convention.
AP conducts surveys of these super delegates, and adds them to a candidate's totals if they indicate their support. But Super delegates can - and do - change their minds during the course of the campaign, so the figures may shift as the race unfolds.
The delegate tracker is updated automatically. There may be a short delay between the delegates being assigned and the totals changing.
