Don’t buy into the false assumption that this question was something other than a ‘gotcha’ question.
Walker recognized it for what it was, a question meant to trap him so they could berate him about it for weeks or even months over his answer.
Here is more from the WP article which explains why his non-answer was the correct one. Notice his dig at the reporter with a reference to a double standard.

On Saturday, Walker suggested that he is being held to a different standard than some Democrats. Citing Teamsters President James Hoffas criticism of the tea party movement at an Obama rally in 2011, Walker wondered why the president has also not been asked by reporters about controversial comments made by figures who are prominent on the left.
Was it Jimmy Hoffa that ripped on the tea party and called them unpatriotic, and the president was standing there and nobody asked him that? Walker asked. To me, it seems Ive had multiple days of an incredible double standard. They dont ask the president about people like Jimmy Hoffa, they dont ask Hillary Clinton about others out there.
My focus isnt on what the mayor said, he continued, referring to Giuliani. My focus is on why I believe, should I choose to get in this election, why I believe we need a fighter.
