KARL: If the Supreme Court establishes that same sex marriage is a constitutional right, does that effectively end this as a political issue in this campaign?
SCOTT WALKER: Well, I personally believe that marriage is between one man and one woman. If the court decides that, the only next approach is for those who are supporters of marriage being defined as between one man and one woman is ultimately to consider pursuing a constitutional amendment.
KARL: So you would favor a constitutional amendment that would say that states are allowed to ban same sex marriage.
SCOTT WALKER: I believe that the decision on defining marriage should be left up to the states, yeah.
