In an unpublished 1988 interview (quoted by Barrett in Rudy!), Helen Giuliani said of her son: "He only became a Republican after he began to get all these jobs from them. He's definitely not a conservative Republican. He thinks he is, but he isn't."
Using a Communist like Wayne Barrett as a source to attack a Republican is contemptable. There are plenty of legitimate sources of anti-Giuliani info to draw from. Using Leftist sources is unnecessary.
