Indiana has 92 Democratic delegates available
Of those, all but nine are what's called "pledged" delegates, meaning they're locked in to voting for a specific candidate on the first ballot.
How they're apportioned is based on the statewide vote tally – if Hillary Clinton gets 55 percent of the vote, for example, she'll get 55 percent of the pledged delegates.
Nine of the delegates are so-called "superdelegates" who can vote for whichever candidate they want.
