There's only one interview technique that matters... Do your homework so you can listen to the answers and react to them and ask follow-ups. Do your homework, prepare.

It's not what happens to you, but how you react to it that matters.

A debate has one purpose, one purpose only, and that is to facilitate the exchange of ideas directly between two candidates, and that's it.

I've always said this and finally I had a chance to demonstrate it: The moderator should be seen little and heard even less. It is up to the candidates to ask the follow-up questions and challenge one another.

He'll listen to anything I tell him, but I don't know how he'll react. I can't guarantee he won't react to something on the field.

I'm an expert on the NewsHour and it isn't how I practice journalism. I am not involved in the story. I serve only as a reporter or someone asking questions. I am not the story.
