Here's the latest from the Democratic primary for Cook County board president.

Ald. Toni Preckwinkle released her second ad today, which includes a surprise cameo:

Kudos to the campaign for injecting a little humor into the spot.  Also, Preckwinkle has scheduled a press conference tomorrow morning to announce "another major endorsement."  (Rep. Jesse Jackson Jr. seems to be a possibility.)

Incumbent Todd Stroger appeared on WFLD's Fox Chicago Sunday yesterday.  He repeated his mantra that he has done a "great job" as board president and also said that his campaign will hit the airwaves with their first ad at some point this week.  Watch it:

In other news, the Sun-Times' Lisa Donovan talked to the Democratic candidates about their regrets and the Chicago News Cooperative's Jim Warren devoted his latest column to the race, expressing some serious cynicism: "[N]o candidate appears to have the management savvy or the will to make enemies of virtually every entrenched group while seeking radical change." 

Finally, the Democratic candidates will meet for an hour-long debate on WTTW tomorrow evening at 7 p.m.
