Clinton’s lead over Sanders seems to be growing in some spots

Hillary Clinton has pulled ahead of Bernie Sanders in the race for delegates awarded in primaries and caucuses.

Clinton eked out the final delegate from Saturday's Nevada caucuses, giving her a total of 52 caucus and primary delegates.

Sanders has 51.

Some of Sanders' supporters have complained that while the two had been tied in delegates chosen by voters, party leaders were tilting the race in Clinton's favor.

Clinton's lead gets much bigger when you include endorsements by superdelegates, who can support any candidate, regardless of whom voters support.

When an Associated Press survey of superdelegates is taken into account, Clinton has 503 and Sanders has 70.
