Here is something you conveniently left out of the same poll:
"More than thirty years ago, the Supreme Court's decision in Roe versus Wade established a constitutional right for women to obtain legal abortions in this country. In general, do you think the Court's decision was a good thing or a bad thing?"
Good Thing: 59%
Bad Thing: 32%
Both(vol.): 4%
Unsure: 5%

What does all this say? It says that people's personal beliefs that abortion is wrong exept in very restricted cases does not mean they will allow those personal beliefs to interfer in a woman's right to choose.
Also, as part of the same polls, I found this:
"If one of the U.S. Supreme Court justices retired, would you want the new Supreme Court justice to be someone who would vote to overturn Roe v. Wade -- the decision that legalized abortion -- or vote to uphold it?"
Vote To Overturn: 29%
Vote To Uphold: 65%
Unsure: 5%
A majority of people want abortion to be legal regardless of their personal beliefs.
