The retraction would have to be huge and repeated often to rebut his videotaped return to his normal lifelong pro abortion position.
I have never seen the video of Romney retracting his statement that he made on CBS.
Maybe someone will post it if it exists.
It was probably someone with the Campaign who clarified Romney's position when asked by the Press.
Doesn't matter anyway, President Infanticide is running the Ship of State nowadays. Romney is just another asterisk in Political History, like McCain.
