I don't hate Giulliani, he appears to be a very likable guy.
However he publicly supports the abomination of abortion. He has my prayers, but not my vote.
He is a practicing Catholic who entertained the Priesthood.
Where he supports Abortion is because he was a public officeholder and it is the Law of the Land.
A law and order type like him would prosecute Abortion to the max if the law made it illegal.
