Presidential Debate

In light of the presidential debate, I would like to highlight a few knowledge issues I'm witnessing currently as I watch it. The entire purpose of the debate is for candidates to discuss the policies and ideals that they would create and maintain while in office. However, there are several flaws in this system. One of the things I have noticed is that the bulk of the debate is refuting each others points and giving out specific facts that divert from the original question. Each time a new question is brought to light, the candidate first to answer immediately veers from the question and instead discusses something that backs up his own political ideas. In reaction the other candidate refutes the statement by subtly insulting what was said and then repeats the same exact pattern of backing up his own political ideas. As they begin to really debate they each tiptoe around the original question, while using facts that serve their own agenda. This creates a somewhat unethical debate that uses justifications and excuses to sway the voters. Granted there are some real issues discussed, but the majority of what is talked about is unrelated to the structure of the debate and its questions.
