This is the new tactic of the left- use the full power of a friendly DA's office in conjunction with the press in order to endlessly harass and smear prominent republicans.
In Wi, Scott Walker was investigated for 2 years under a 'john doe' investgation initiated by the milwaukee DA's office. Several republicans in key positions had their offices and homes ransacked with files and computers confiscated. No charges were ever brought and the cases were eventually ordered shut down by higher courts. The goal was never to find a crime but to use the power of the legal system to make life a living hell for a lot of people.
This amounts to nothing more than political persecution, even more brazen than the IRS scandal.
Let's go back a few more years in Wisconsin. Democrat Senate Majority Leader Chuck Chvala is caught extorting millions of dollars from lobbyists. It's being laundered through the Democrat Party in Kansas, funneled to a Chvala-controlled group in DC, then sent back home to be given to loyal supporters of Chvala in their senate campaigns.
The FBI is looking at Chvala for interstate money laundering. He faces 19 felony counts, including 17 counts of extortion.
In steps loyal Democrat Milwaukee County DA Michael McCann. The grand jury never hears about the extortion. Chvala is charged with using a state employee on state time for campaigning. He gets 9 months of house arrest, meaning he can go to work, he can go shopping, and can have parties at his house. He is barred from being a lobbyist for three years (he's now a well-paid lobbyist to his old buddies).
The left's tactics isn't just to use the DA's and courts to harass and smear Republicans. It's also to use them to let Democrats walk.
