Is the Gov. From the State of Koch too big to jail?

I wonder why there's no mention of the Koch Bros. in S-T's coverage of Gov. Walker's crooked campaign fundraising tactics. Walker is after all, the Gov. from Koch.

Remember when a prankster called Gov. Walker  posing as David Koch and mentioned "special interests" the governor didn't flinch. He didn't have to be told in whose interests he was working. Koch had bankrolled his campaign and contributed over $1 million to the Wisconsin Governor's Assoc. The Koch-funded Wisconsin T-Party were his campaign workers.

Prosecutors are now on his trail but teacher-bashing, union-busting Walker may be too big to jail. He's one of Limbaugh Party's main hopeful's for White House run in 2016. NYT reports:

...the Club for Growth become “a hub,” according to prosecutors, for coordinating political spending by the Walker campaign and an array of outside groups. These ranged from the Republican Governors Association to Americans for Prosperity, the conservative advocacy group co-founded by the billionaire industrialist David H. Koch and financed by the political network overseen by Mr. Koch and his brother Charles.

Back in 2011, I had to hand it to Walker for truth-telling in a to talk with supporters at the stodgy, tie-only Union League Club. A group of protesters had donned business attire and sneaked inside the meeting, greeting Walker with chants of, "Union busting -- it's disgusting!" before they were finally escorted out by security. But Walker was clever enough to retort:

“I found it amusing to be referenced in the same vein as Rahm Emanuel, the mayor, but, really, some of the reforms he’s trying to do here echo the things we try to do in the state of Wisconsin and I give him credit for that despite the fact I’m a Republican and he’s a Democrat." 

Couldn't have said it any better, myself.
