"I struggled with it myself for a long time, but I came to realize life is that gift from God," Mourdock said at the debate, after saying he believes in abortion only when the mother’s life is in danger. "And I think even when life begins in that horrible situation of rape, that it is something that God intended to happen."

He has since clarified that he meant that "God creates life."

"Rape is a horrible thing, and for anyone to twist my words otherwise is absurd and sick," he said.

The Democratic Senatorial Campaign Committee did not release what the presidential numbers were in the poll, making it harder to judge how accurate it is. It will take a few days and some nonpartisan polling to see the long-term impact of Mourdock's comments, but the poll suggests that he may have done serious damage to his campaign.

The poll of 446 likely voters was conducted by the Democratic firm Anzalone Liszt Research from Oct. 24-25 and has a margin of error of plus or minus 4.6 percentage points.
