Five US states hold primary elections on 15 March in what may be a defining moment in both parties’ nomination races. Here are the results so far and links to watch all the votes being counted.
Results of 15 primaries: Clinton and Trump in Florida, Clinton and Trump in Illinois, too close to call in Missouri, Clinton and Trump in North Carolina, Clinton and Kasich in Ohio.
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.
