If folks rely on these "debates" to form an opinion as to who they should vote then they are better off not voting at all.
There are plenty of other ways to understand which side of the issues each candidate comes down on. Both have “records”, websites and literature etc. The voting public ought to take a little more responsibility in deciding who they want for a leader then simply turning on CNN or Fox.
If they rely on scripted events like conventions, commercials, news sound bites or "debates" to decide who they should vote for they wont be making an informed decision. Lazy people shouldn’t vote.
