While Mitt Romney's sons (he has five--no daughters) are actively blogging and touring the country stumping for their father's campaign, Rudy Giuliani's own children either won't help, as in his son Andrew's case, or are tenatively supporting Obama for president, according to this CNN article.

Who knows a person better than their children and their spouse. Romney's are fully behind him. Giuliani's are not (except for spouse #3). That should tell the American public volumes about the comparative character of these two men.
