KING: Lose your balance. Gay marriage, you tell us in the book that during the 2004 campaign you talked to George about not making it a significant issue. Do you think we should have it? BUSH: Well, I think we ought to definitely look at it and debate it. I think there are a lot of people who have trouble coming to terms with that because they see marriage as traditionally between a man and a woman. But I also know that, you know, when couples are committed to each other and love each other, that they ought to have I think the same sort of rights that everyone has.
KING: So would that be an area where you disagreed?
BUSH: I guess that would be an area that we disagree. I mean, I understand totally what George thinks and what other people think about marriage being between a man and a woman. And it's a real, you know, reversal really for that to accept gay marriage.
KING: But you do?
BUSH: But I think we could, yeah. I think it's also a generational thing.
KING: You think it's coming?
BUSH: Yeah, that will come, I think.
KING: How about choice?
BUSH: That was the -- I write in the book about the very first question I got on the morning of George's inauguration, from Katie Couric, who asked me two questions about abortion. That was the social issue in 2000 that everyone got asked about. And then I think gay marriage was the social issue in 2004. And I was say probably in the more recent election as well.
She asked me if -- she asked two questions about abortion, and then she asked me if I was for the overturn of Roe versus Wade. And sort of everything went through my mind. This was the very morning my husband was about to be inaugurated. And I thought, do I really want to start my husband's presidency, you know, suggesting that a Supreme Court rule being overturned. And I said no.
And I think it's important that it remain legal, because I think it's important for people, for medical reasons and other reasons.
KING: So you -- that would be two areas of disagreement.
KING: But you weren't so expressive during the White House day.
BUSH: About those issues, you mean?
BUSH: No, not really. I talked about those issues. I was asked about those issues a lot. Not so much about abortion, but in the 2004 election, a lot about gay marriage. That was the social issue that really animated that election, I think. KING: When you discuss it with your husband, is it argumentative?
BUSH: No. Not at all. I mean --
KING: He understands?
BUSH: Yeah, and I understand his viewpoint. I really do. I understand his viewpoint. And he understands mine.
