Ouch. Rudy's family values bit him in the *ss again.

There's one vote that Rudy Giuliani definitely can't count on in his 2008 presidential bid: his own daughter's. According to the 17-year-old Caroline Giuliani's Facebook profile, she's supporting Barack Obama.

On her profile, she designates her political views as “liberal” and — until this morning — proclaimed her membership in the Facebook group “Barack Obama (One Million Strong for Barack).” According to her profile, she withdrew from the Obama group at 6 a.m. Monday, after Slate sent her an inquiry about it.

…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.
