CNN: "So, who won the Republican debate?"

[Mass]

16. No, Rubio was asked how he was squaring a culture of life and accepting abortion during rape

and rushed to say he was not accepting it.

As for Walker, he basically said he did not support a health exception and implied it was ALWAYS possible to preserve the health of the mother without getting an abortion.

They were not asked to elaborate on those specific points (after all, it was a Fox debate).

Here is for Rubio

When moderator Megyn Kelly suggested Rubio was in favor of rape exemptions in abortion bans, Rubio pushed back and argued he never supported such an exception.

"I have never said that, and I have never advocated that," Rubio said. "I have advocated that we pass a law that says all human life at every stage of development is worthy of protection."

It was widely assumed Rubio supported exemptions in the case of rape and incest because those exceptions were included in legislation he introduced in 2013 prohibiting abortions after 20 weeks of pregnancy in 2013.

And Walker

“Well I’m pro-life,” the Republican candidate said. “I’ve always been pro-life. I’ve got a position that’s consistent with many Americans out there in that I believe that that is an unborn child that’s in need of protection out there. And I’ve said many times that that unborn child can be protected and there are many alternatives that would protect the life of the mother.”
Moderator Megyn Kelly had asked Walker: “would you really let a mother die rather than have an abortion?” She added that 83 percent of voters are in favor of a “life exception” and questioned whether he is too out of the mainstream on this issue to win the general election
