The four major Chicago mayoral candidates debate at 7 p.m. Jan. 27; this will be the first one where front-runner Rahm Emanuel joins the group running in the Feb. 22 primary.

The debate will be hosted by the Chicago Tribune and the City Club of Chicago. Candidates at the debate will be Gery Chico, Miguel del Valle, Emanuel and Carol Moseley Braun.

Micah Materre, WGN-TV News at Nine co-anchor, and Bruce Dold, Chicago Tribune Editorial Page Editor, will moderate.

The debate is excluding other candidates because of poor showings in a Chicago Tribune/WGN-TV poll of Chicago voters conducted Dec. 10-13, 2010.

For view plans, per a release: "The debate will be broadcast live on WGN-TV (local signal), CLTV, WGNTV.com, chicagotribune.com, and WGN Radio (AM720) at 7 p.m. and will run for 58 minutes, commercial free."
