The Cook County Democratic Party will meet Thursday and Friday for their “pre-slating” meeting, an opportunity for candidates of countywide and statewide offices to make their pitches to the 80 Ward and Township Committeemen, as they seek the County Party’s endorsement. The speeches, open to the media at 134 N. LaSalle, in the 7th floor conference room, promise to deliver drama and a couple of political shifts. The County Party will hear candidate’s pitches this week, then meet again on August 10 and 11 to vote on slating.
