Appearing Sunday on CNN's State of the Union, Wisconsin Governor Scott Walker boasted that unlike his rivals for the Republican presidential nomination he answers questions, then refused to answer whether he believes being gay is a choice.

Walker, like Ted Cruz, the senator from Texas, has said that he backs a constitutional amendment that would allow states to individually decide whether to issue marriage licenses to gay and lesbian couples.

After telling host Dana Bash that “one thing that people find unique … is [that] I actually answer questions,” Walker said that he has no opinion on whether people can choose their sexual orientation.

“That's not even an issue for me to be involved in,” Walker said. “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.”

Bash asked how he intends to work for gay Americans without understanding their needs.

“I don't have an opinion on every single issue out there,” he 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.”
