Durkin has brought in the highly capable Mike Zolnierowicz to handle things on his campaign. Mike Z, as he’s known in political circles, was Governor Rauner’s deputy campaign manager, then his first chief of staff, then ran Rauner’s massive campaign apparatus until this past July, when Z resigned during Rauner’s Great Summer Staff Purge (and eventual re-purge) of 2017 and joined Xpress Professional Services as its political director.
