MADISON, Wis. – If Democrats see the seemingly endless John Doe investigations as a big gun in their political arsenal against Gov. Scott Walker, the latest poll numbers suggest this not-so-secret weapon isn’t hitting the mark.

Mike Tate and crew at the Democratic Party of Wisconsin haven’t merely been rooting for bombshell revelations against Walker in the secret probes, they’ve been using the investigations as one of their major narratives this election year.

“You can assume they’re finding serious acts of wrongdoing,” Tate, the chippy chairman of the state Dems, told the Milwaukee Journal Sentinel’s Dan Bice in November, following news the Democrat-led Milwaukee County District Attorney’s office had launched another John Doe into conservatives.
