Speaking from a reality based perspective and my experience as a son, brother, father, and husband- Children often turn out the way they do in spite of what kind of parents raised them. My aunts and uncles all turned out different, my siblings and I, and my children will growup to be their own individuals as well. My best friend probably comes from the best family I know and his parents raised them well. Yet half of his siblings are criminals.
Huckabee may or may not be a good father.
However, it is his POLICY failures that matter the most, not his personal ones. He has plenty of failures as a Governor without even needing to get into his personal ones. The same goes for Giuliani when people want to go all nutjob on his crossdressing and the fact that he actually knew homosexuals without attempting to stone them to death.
