1 No candidate likes to prepare the same way
Bush believed that full-length mock debates were a waste of time. We had only one before his first debate with Al Gore, instead concentrating on shorter, single-issue-focused mini-debates. Dick Cheney insisted on full-length mock debates that were as close to the real thing as possible, even starting at the same time of night as the real thing. Both approaches worked.
2 Small is good
For some reason, people find debate preparation fascinating and clamour to be involved. Nothing destroys a prep faster than too many opinions. Keep it small and get good at saying no to even the best intentioned.
3 Have a clear strategy, with defined goals for every debate
This can't be something vague, like "win the debate". Analyse the strategic imperatives of the moment and formulate three or four specific goals. They can be offensive (disqualify opponent's tax plan) or defensive (deal with X scandal and put it to rest). Inevitably, much of a debate will not matter, just as there are a lot of three-and-out plays in a football game. It's up to each candidate to create the few moments that will define the debate. If left to chance, odds escalate that those moments will favour your opponent.
4 Control the tone
There is always a threshold question for every debate prep team: Do we want a hot or cool debate? It's a critical decision that can drive much of the prep. Even against the most aggressive questions from a moderator or assaults from an opponent, a candidate can always de-escalate or escalate, if prepared. When it's a candidate's turn to speak, it's like that moment in a basketball game when a player has the ball and is setting up for a play. I always tell candidates to take a beat, see the court, enjoy the control. Most mistakes are made in a debate when a candidate is following, not setting, the rhythm and intensity of exchanges. That's how a candidate gets baited into a heated response. You have a minute-and-a-half to three minutes to say anything you want. Relax, take a breath, run your play.
5 Forget "zingers" or scripted lines
Every candidate loves to have an arsenal of one-liners, both defensive and offensive. This is an understandable but terrible instinct. Debates are arguments, and the key to a great debate is to understand your argument and prosecute it. Most actors can't land great lines in one take. Looking for that perfect chance to deliver a great line takes a candidate's mind out of the argument. For every great debate moment involving a scripted line, there are countless lost moments when candidates were preoccupied with trying to get a line in.
6 Don't make policy news in a debate
In the pressure cooker of a big debate, there can be a tendency to start ad-libbing policy as an answer to a tough question (as when John McCain announced a massive mortgage buy-back plan out of the blue while debating Barack Obama). This leaves a campaign scrambling to put together backup, talking points and white papers on the fly. Use a debate to say what you have said before, just better.
7 Don't swim upstream
We've all seen this happen, and it never works well: A candidate takes time to correct the record on something said earlier by an opponent or moderator. Nine times out of 10, the audience has forgotten whatever was said, and bringing it up again only reminds them and increases the damage. Let it go. (If I were prepping Hillary Clinton, I'd advise her to hit Donald Trump with constant charges. He responds to everything.)
8 Have fun
Very few people make it into the Super Bowl of presidential debates. It's taken more work than anyone can imagine. You've earned it. Embrace it. Few presidential races are decided by debates. So you might as well have the time of your life.
