The Democratic National Committee on Saturday will elect a new chairman in balloting that could go multiple rounds and is governed by clearly defined procedures.

The DNC on Friday detailed a schedule during an afternoon conference call that calls for the marquee contest, the chairman’s race, to be decided first before voting for lower offices, including finance chairman and a collection of vice chairmen. To win, candidates must secure the support of 50 percent plus one of the 442 eligible voting DNC members who cast ballots during each round of balloting.
