Scott Walker, the latest GOP candidate to announce his presidential aspirations, was able to tip-toe around the question of his running for a while--but he's not going to be able to "walker" away from the big questions for much longer.

On CNN's State of the Union Sunday morning, the Wisconsin governor was asked by corespondent Dana Bash whether he believed being gay was a choice. The self-proclaimed "most scrutinized politician in America", who has said people like him because he "actually answers questions," didn't have an answer for Bash.

"Oh, I mean I think that's, th--  that’s not even an issue for me to be involved in. The bottom line is, I’m going to stand up and work hard for every American regardless of who they are, no matter where they come from…no matter whether they vote for me or not," Walker told Bash.

The question from Bash came as she was asking the GOP candidate about his recent remarks on banning gay Boy Scout leaders.  Not content with his answer, Bash smiled at Walker, telling him he wasn't really answering her question.

Bash continued to ask Walker how he intended to "stand up and work hard" for all Americans if he didn't "understand" or "have an opinion on who they are and where they're coming from."

“I don’t have an opinion on every single issue out there,” Walker answered.  “I mean to me that’s — I don’t know. I don’t know the answer to that question. So I’m saying, from an opinion standpoint, I don’t know what the answer to that is. And I’m going to spend my time focused on things that I do know and what I can work on.”

It is clear, especially following last month's Supreme Court decision, that same-sex marriage and LGBT issues will be a crucial point for 2016 presidential candidates. Bash's question --inherently more personal and aimed at a deeper level of the issue -- may be a foreshadowing of the topic going from mere policy talk, to people wanting to know how their leaders actually view the people and the issue.

Walker's answer, though diplomatic, may have been more telling of his family's division on the subject.

Earlier this month Walker's wife Tonette said in an interview that she and her husband do not agree on same-sex marriage -- that even their sons were "disappointed" by his position.

Fellow GOP candidate Rick Santorum didn't let the public marital disagreement go unnoticed, telling the Daily Caller that "spouses matter," and the Walkers not being "in-synch" could lead to being "as active on those issues."

There is one thing that is for sure: with too many examples of public figures being lampooned for any indication that they don't agree/believe with something, the candidates and their teams are sure to carefully script any response around the minefield of controversial topics to come.
