Elizabeth Evans, the executive director of the Illinois Network of Charter Schools, seems to be a casting a “no” vote for Arne Duncan as ed secretary.

Her plea for Duncan to stay in Chicago illustrates that as Obama picks the best and brightest for his cabinet, those folks leave behind a big void that will have to be filled. On the education front, Obama’s pick of Arizona Gov. Janet Napolitano for the homeland security cabinet post leaves one of the biggest voids so far.
