Scott Walker has not begun to answer the critical questions raised by the release of 28,000 pages of emails and more than 400 legal documents associated with investigations of wrongdoing by his aides and political allies.

He has simply repeated carefully crafted talking points that avoid dealing with the questions about what he knew of:

* Secret email accounts used to conceal illegal activity in his Milwaukee County executive office.

* Secret schemes to coordinate between his 2010 gubernatorial campaign and Milwaukee County appointees who were supposed to be serving the public.

* Crude racist messages sent by his top aides.

* Why, after he became governor, he continued to work with aides who he knew were under investigation for official wrongdoing, and with aides he might reasonably have suspected were under investigation.

Walker has not been nearly as forthcoming as was Chris Christie after an aide’s email exposed an apparent link between the New Jersey governor and lane closings that stalled traffic for days in a city where the mayor had refused to endorse Christie.
