ELI5: What are superdelegates and what does it mean that Hillary already has so many?
gpt
At the Democratic National Convention, a group of people called "delegates" will decide who the Democrats will run for president. About 80% of these delegates are elected by Democratic voters in primary elections and caucuses. The other 20% are not elected by voters, they are made up of prominent Democratic politicians and party officials. Most of these are backing Hilary, which puts Bernie at an automatic disadvantage. It means he doesn't have to just win more primaries than Hilary, he has to win a lot more and by a wide margin.
