An idea to produce a meaningful presidential candidate debate

If I were the emperor of the world — in charge of all things regarding presidential candidate debates — here are the simple rules I would have for my debates:

1. The moderators will ask the candidates questions on a variety of topics designed to get them to speak specifically about what actions they will take to make the world a better place four years from now.

2. Candidates will be forbidden to mention their opponents. If they try, they will be cut off.

It would also be interesting to have the audience be comprised of undecided voters wired to determine their responses — favorable and unfavorable — to the various pronouncements  from the candidates.
