Asked by Channel 3000 last week whether he wanted all abortions made illegal, Walker responded , "That's not even an option in the state. The Supreme Court more than 40 years ago ruled that is not an option."

And in the campaign's first gubernatorial debate, he echoed statements from his ad, simply saying he is "pro-life" and he "can only imagine how difficult it is" for a woman to decide whether to end a pregnancy. He defended the bill he signed requiring women to get an ultrasound and have the fetus' visible organs and features described to them before having an abortion, touting it as a measure to protect women's health and safety, and said it leaves the final decision to a woman and her doctor.
