Chicago Magazine's Carol Felsenthal has a fascinating article up about Penny Pritzker's timely departure from the CPS Board of Education, the delay in naming a replacement, and who the replacement -- or replacements -- might be.
According to Felsenthal, Pritzker left in March to avoid the raucous school closing hearings that have followed (and wasn't questioned about her role on the Board during her confirmation hearing), Emanuel declined to name a quick replacement because he was confident that there wouldn't be any ties with six members, and some possible (but unlikely) replacements for Pritzker include Jitu Brown (Karen Lewis's idea) or Dwayne Truss or Wendy Katten, or Amy Rynell. Or, sure, an elected board.
One thing that Felsenthal doesn't address is the possibility that Emanuel will remove current Board members -- say the two who voted against the Von Homboldst closing (which were they, again?).
Mayors in other cities with appointed Boards have done similar things, for similar infractions.
