It's not news that Rudy and his two children, Caroline and her 21-year-old brother Andrew, have a rocky relationship. Caroline and Andrew are the children of Donna Hanover, Rudy's second wife. In March, Andrew, who is a junior at Duke, told the New York Times that he and his father had been estranged for some time, and he has spoken candidly about his objections to Giuliani's marriage to Judith Nathan. And after the wedding, the Times reported, Giuliani also stopped attending Caroline's high-school events. Though he went to her high-school graduation, he left without speaking to her and did not join in the post-graduation family celebration, according to the New York Daily News.
Caroline's Facebook profile does not reveal why she doesn't want her father to win the White House. She has not responded to e-mail questions from Slate.

Over the past several months, media reports have noted a rift between Giuliani and his two children (21-year-old Andrew and Caroline). At the core of their troubled relations is believed to be the former New York City Mayor's divorce from their mother, Donna Hanover, and their relationship with Giuliani's third wife Judith Nathan.
