Back in 1996, Fred was in favor of over turning Roe, and he favored states passing reasonable restrictions such as parental notification and restrictions on late term abortions. Fred also spoke out against federal funding for abortions. Fred was against the federal government criminalizing abortions, which in reality is something that won't be on the table anytime soon. Romney supporters like to characterize this as pro-choice just as Romney was, but that simply was not the case. Romney spoke out against any restrictions and thought Roe was great law.
I think he always specified that he was against criminalizing the WOMEN. He never mentions anything else, such as going after doctors.
