Las Vegas Valley
During the Democratic debate in Las Vegas, the candidates for the Democratic presidential nomination were asked if the "person with the most delegates at the end of the primary season" should be the nominee for the Democratic party, even if the candidate is short of a majority of delegates. All candidates except Bernie Sanders answered the question with no. This is important in particular because if no candidate has a majority on the first ballot, 500 superdelegates that aren't appointed through primaries can vote in the second one.
