The Point: Parties use their national conventions to formally nominate candidates for president and vice president. Party leaders showcase their nominees, and the prime-time speeches by the candidates and prominent politicians win over major television audiences. Democrats also will adopt the party's platform, which spells out policy principles but has no binding effect. The Location: The Wells Fargo Center, home to the NHL's Philadelphia Flyers and the NBA's Philadelphia 76ers, is the convention site. Democrats are hoping the city's historical role in the founding of American democracy will serve as a powerful backdrop for the themes they'll address. Who's Going: More than 5,000 delegates are among the 50,000 people set to be in Philadelphia. They include alternates, lawmakers, special guests, journalists and protesters. Among the delegates, about 15 percent are superdelegates, mainly members of Congress and members of the DNC. Those Emails:The convention was shaken Sunday before it even began by fallout from 19,000 hacked DNC emails published online, some suggesting the party favored Clinton over Sanders in the primary. Wasserman Schultz, long accused by Sanders of rigging the primary for Clinton, said she'll resign at the end of the convention. The Schedule: First lady Michelle Obama and Bernie Sanders are set to speak Monday. Former President Bill Clinton will speak Tuesday. On Thursday, Chelsea Clinton will introduce her mother for her speech accepting the Democratic nomination. Kaine will give a speech introducing himself to the country. Officials haven't yet said when, but the running mate typically speaks Wednesday. The Entertainment: Snoop Dogg, Lady Gaga, Lenny Kravitz and Cyndi Lauper will make appearances. Fergie will perform at The Creative Coalition's gala. Roll Call: States will get a chance to announce how their delegates are voting in the formal roll call Tuesday. Sanders delegates are pushing to have their votes fully tallied. Clinton arrives in Philadelphia with 2,814 delegates to Sanders' 1,893. There's a total of 4,763, and it takes 2,382 to win the nomination.
