The emission took us to old debates and showed us how some won and others lost the presidential debate "lessons learned"
One that impressed me a lot is not just hearing but seeing, Bill Clinton going near the public, looking, interacting with them "working them" very effective, at the same time, Bush did not even understand the auditor's question and kept on speaking about deficit and the state, not adressing the woman's personal wory. Kept himself far from the audience.
Another example was how Obama looked to McCanain, who never looked to him or the audience.
Also, very impressive was how the (we now know) ill Kennedy looked strong and young, and Nixon (having just injured his knee) ill and old. And so on.
Of course, the message matters. But also, how you deliver it.
