Was thinking about this before, if you could ask pointed questions, allowing for reasonable answers, (not "hey, Romney, why do hate the poor?" or "hey, Obama, why do you hate America so much?") of each of the candidates, what would you ask?
Here goes, for me:
Obama/Biden to Romney/Paul "Do you think there is a difference between rape and "forcible rape"?"
Romney to Obama "Why is Guantanamo Bay still open?"
