On July 25, these superdelegates will cast votes at the Democratic National Convention for whomever they want, regardless of primary and caucus outcomes. Democrats like to describe superdelegates as mostly elected officials and prominent party members, including President Obama and former Presidents Bill Clinton and Jimmy Carter.
But this group, which consists of 21 governors, 40 senators and 193 representatives, only makes up about a third of the superdelegates. Many of the remaining 463 convention delegates are establishment insiders who get their status after years of donations and service to the party. Dozens of the 437 delegates in the DNC member category are registered federal and state lobbyists, according to an ABC News analysis.
