In Walker's Wisconsin, it's never "agree to disagree"-- it's agree to agree with the Governor.
If you don't, you'll end up like former Republican State Senator Mike Ellis. Ellis was Wisconsin's longest serving Republican state senator and, although he historically had been considered a staunch conservative, after the Walker caliphate was installed in 2011, he came to be viewed more and more as a moderate because he dared to be something other than a yes man.
So, Walker had him whacked-- at least that was the rumor. No, no, no silly rabbit, not that kind of whacked-- he killed his political career by having the notorious political mercenary, James O'Keefe (of New Jersey) pay a visit to Wisconsin and bait Ellis into saying embarrassing things into a hidden camera. (So embarrassing, in fact, that Ellis decide not to seek re-election in 2014.)
At the time, everyone in Wisconsin was scratching their collective cheeseheads wondering why in the hell James O'Keefe would be interested in A) putting a hit on a fellow Republican and B) wasting his time with an obscure state Senator in Wisconsin. The only obvious answer: Scott Walker was tired of Ellis being only a 90% head-nodder and put out a hit on him. But like most rumors, there wasn't any proof tying Walker to O'Keefe and it faded into the political ether.
