Daniel Bice’s Milwaukee-Journal Sentinel column begins:

Milwaukee County prosecutors have opened a John Doe investigation into voter bribery allegations stemming from last month’s state Senate recall elections, according to sources.

Details of the secret investigation are sketchy, but it is clear the Milwaukee County district attorney’s office is investigating charges that Wisconsin Right to Life offered rewards for volunteers who signed up sympathetic voters in the recall races. Several people familiar with the investigation said subpoenas were being distributed “like candy.”

Prosecutors had earlier acknowledged that they also were looking into complaints about get-out-the-vote block parties sponsored by a liberal group, Wisconsin Jobs Now.

But Assistant District Attorney Bruce Landgraf, who investigates election law violations, now won’t discuss either matter.

“Absolutely no comment,” Landgraf said.
