Chicago Ald. Michelle Harris and U.S. Rep. Robin Kelly are vying to be the next chair of the Democratic Party of Illinois.

Like the state House of Representatives did in early January, the Democratic Party of Illinois is set to enter a new era Wednesday, when members of the party select a replacement for former chair Mike Madigan.

Madigan, who was first elected chair in 1998, resigned last month, causing a mad dash to replace him as head of the state party.
