While I would never, ever dispute that Brunner is far preferable to either Akin or Steelman, I still don't know that he's really all that great. He was quoted as saying that Mitt Romney "is conservative enough for me" and is "just the kind of leader we need right now" (http://universitycity.patch.com/articles/last-gop-senate-pri... or http://voices.kansascity.com/entries/advance-strong-candidat...).
And to see his position statements he seems to more concerned with, for example, providing our soldiers with a clear mission and clear goals when sending them overseas rather than refraining from sending them anywhere unless we are providing them with a clear declaration of war (http://johnbrunner.com/brunner-on-the-issues-defense/). Also not sure that he really cares about the Fed or the income tax - he wants to "reform the US tax code to produce a smaller, flatter tax rate" (http://johnbrunner.com/brunner-on-the-issues-taxes/), but, as far as I know, does not really care about eliminating the income tax or the IRS.
But to be absolutely clear, he is, without a doubt, better than either Akin or Steelman.
