Allowed to duck ethanol issue, will Walker evade vaccination issue, too?

OK - - Walker is allowed by media to evade a position on the ethanol issue so dear to the hearts of Iowans who mistook him for an excitable Dan Quayle 2.0 or were awestruck that he had better hair than Donald Trump (and who doesn't?)  - - but which reporter will try and see if Scott Walker stands with the vaccine-optional-for-kids-freedom panderers, like Chris Christie and Rand Paul, or the suddenly more reasonable Dr. Ben Carson?
