The Chicago Federation of Labor, the umbrella organization for Chicago and Cook County's labor unions, publicized a selection of endorsements in countywide races in the upcoming March 20 primary. The group neglected to endorse in a few key races, opting to write “TBD” for the 2nd, 4th, 5th, 8th, 10th, 11th, and 16th district races, and for county assessor.
