According to CNN, he's still for public funding of abortions:
"There must be public funding for abortions for poor women," Giuliani says in the speech that is posted on the video sharing site YouTube. "We cannot deny any woman the right to make her own decisions about abortion."
When asked directly Wednesday if he still supported the use of public funding for abortions, Giuliani said "Yes."
I presume that means a definitive breach with the pro-life base.
