There are a lot of people playing amateur detective on Walkergate, but I'll leave the serious sleuthing to Dist. Atty. John Chisholm's office and the FBI, who seem to be doing pretty well so far.
That said, a couple of more observations:
Walker's repeated claims that he knew nothing are very hard, if not impossible, to believe.
The day (May 14, 2010) the Journal Sentinel ran a story about Darlene Wink doing political work on county time, Walker sent an email to aide Tim Russell that said we can't have any more stories like this, and no more laptops in the office. Does that sound like Walker knew staffers were using laptops to do political work? It certainly does.
The lengths to which his staff went to break the law, setting up a second, secet, wireless computer network to do their dirty work, make it clear they knew what they were doing was illegal.
Did Walker know? Did Tom Nardelli, the chief of staff? It would have been hard -- maybe impossible -- for them not to know something was going on.
