Typically, in a primary, delegates are elected by voters to cast their vote at the nominating convention on behalf of those voters. “Superdelegates” go to the convention just like regular delegates but are free to support any candidate they like, independently of who their constituents prefer. One of Hillary Clinton’s tactics in keeping Joe Biden out of the presidential race was to “leak” her massive support from superdelegates. As of November 13th, she had over 359 committed delegates, before voting had started.
In New Hampshire, where only 26 votes have been counted, Hillary has a 6-0 delegate lead over Bernie Sanders. With only 32 delegates at stake in the state, this amounts to an 18.5% lead over her rival. As a result, (assuming the remaining 2 superdelegates split between the Secretary and the Senator) Bernie Sanders needs to win 62.5% of the popular vote in New Hampshire just to break even with his opponent. If they tie the popular vote count, Clinton walks away with 46% more delegates than Sanders.
While this certainly leads to increase Hillary’s air of inevitability of winning the nomination (she has an incredible head start) it has the potential to disillusion Sanders supporters who may feel that they were cheated by the system that didn’t count their votes. Just like her fundraising from Wall Street, which Hillary needs even though it is an albatross, her support from superdelegates poses the risk of being a catch-22, where she is damaged with them but needs them to win.
