Walker, self identified as an Independent, ran on the promise to cut government spending 16%. Which clearly, and without a doubt, distanced himself from establishment republicans and democrats. 
Since his election to office he has failed to submit a budget that cuts spending 16%, which Vince and the democrats are happy with. Conversely, he spent 55 million on an imaginary gas line project which the the republicans are happy with; and continues to hire non-essential employees which the Vinny and the AFL-CIO and democrats are happy with.
Self identifying as an Independent doesn't mean one is good at catering to different groups of people. It means that when it comes to leading and legislating that you'll make the difficult choices and make decisions based on the realities at the time and that reflect the will of your constituents. Which is what Reinbold does well and Walker only talks about doing.
