Ohio gender gap poll likely explains Romney's abortion flip-flip.

Plus a Bloomberg poll said women were moving toward Romney on economic issues but holding back on social issues, especially abortion, confirmed by other pols.

So Romney stated in front of cameras that he has no abortion legislation in mind.  Which his campaign staff then routinely denied (following what is now a well-established pattern). Ryan also then said their position on abortion has not changed.

Romney's previous positions have been that he is absolutely against abortion. That he does not support abortion to protect a woman's health. That he would appoint justices to make abortion illegal. Plus, he is a devout Mormon, and the Church of Latter Day Saints opposes abortion. 

Romney has developed a well-established tell-them-everything strategy based on lying and then retracting those lies, which has been working well through many iterations now. He tells a group what it wants to hear, then his staff issues an official statement saying it was a mistake and his position is actually something else. A brisk, practiced flip-flip maneuver. If you remember from that Pew poll farther down the screen that only 54% of Americans even know the Republicans control the House of Representatives, you can see how he can get away with this attitude toward voters. 

In any case, although it's very hard to know what he might do in most cases, given where he comes from, a strict Mormon background, I believe anti-abortionists can fairly safely vote for him. They may have to wait for if and when actual action becomes politically expedient, though. Or maybe not.
