Could you get a link to Romney’s web site where he says he is pro-choice? It’s hard to read an audio file.
But, here's the text that is referenced in the audio:
Mitt Romney, 1994:
“I believe that abortion should be safe and legal in this country. I have since the time that my mom took that position when she ran in 1970 as a US Senate candidate. I believe that since Roe v. Wade has been the law for 20 years, that we should sustain and support it, and I sustain and support that law, and the right of a woman to make that choice.”
Mitt Romney, May 2012:
"Mitt believes that life begins at conception and wishes that the laws of our nation reflected that view. But while the nation remains so divided, he believes that the right next step is for the Supreme Court to overturn Roe v. Wade – a case of blatant judicial activism that took a decision that should be left to the people and placed it in the hands of unelected judges. With Roe overturned, states will be empowered through the democratic process to determine their own abortion laws and not have them dictated by judicial mandate."
Here's the text from the Roe vs. Wade majority opinion:
"The appellee and certain amici argue that the fetus is a 'person' within the language and meaning of the Fourteenth Amendment. In support of this, they outline at length and in detail the well known facts of fetal development. If this suggestion of personhood is established, the appellant's case, of course, collapses, for the fetus' right to life would then be guaranteed specifically by the Amendment."
-- Justice Harry A. Blackmun, Roe vs. Wade, 1973
Here is one web page. I bolded what I think is relevant -my thoughts follow the material from Romney's website.

Abortion
Mitt Romney is pro-life. He believes it speaks well of the country that almost all Americans recognize that abortion is a problem. And in the quiet of conscience, people of both political parties know that more than a million abortions a year cannot be squared with the good heart of America.
Mitt believes that life begins at conception and wishes that the laws of our nation reflected that view. But while the nation remains so divided, he believes that the right next step is for the Supreme Court to overturn Roe v. Wade – a case of blatant judicial activism that took a decision that should be left to the people and placed it in the hands of unelected judges. With Roe overturned, states will be empowered through the democratic process to determine their own abortion laws and not have them dictated by judicial mandate.
Mitt supports the Hyde Amendment, which broadly bars the use of federal funds for abortions. As president, he will end federal funding for abortion advocates like Planned Parenthood. He will protect the right of health care workers to follow their conscience in their work. And he will nominate judges who know the difference between personal opinion and the law.
Because the good heart of America knows no boundaries, a commitment to protecting life should not stop at the water’s edge. Taking innocent life is always wrong and always tragic, wherever it happens. The compassionate instincts of this country should not be silent in the face of injustices like China’s One-Child policy. No one will ever hear a President Romney or his vice president tell the Chinese government that "I fully understand" and won’t “second guess” compulsory sterilization and forced abortion.
Americans have a moral duty to uphold the sanctity of life and protect the weakest, most vulnerable and most innocent among us. As president, Mitt will ensure that American laws reflect America’s values of preserving life at home and abroad.
My thoughts on this:
In essence and in principle, Romney considers a Supreme Court decision issued under the penumbra of privacy as the law of the land in regard to the protection of life.
Further, he maintains that life, an inalienable right endowed us by our Creator, should best be decided by individuals at the State level. Again, in essence and in principle, Romney implies that the inalienable right to life is something to be decided via the democratic process (at the proper level e.g. the States) RATHER than life being an inalienable right to be protected by and at all levels of government.
In a nutshell, this is a morally devoid Pro Choice position very similar to the position advanced by Libertarians.
