He was inserting stump speech lines into the debate last night, something one isn't supposed to do at a Presidential Debate.
Style: Cluttered, jumpy, and often muddled. Frequent coughing early on helped neither his arguments nor his image. Jokes about being deaf and anecdotes about Normandy and George Shultz seemed ill-advised - even his pen was old. His presentation was further hindered by his wandering discussion of the differing heights of North and South Koreans and his angry assertion about how well he knows Henry Kissinger.
Fell into the classic politician's trap of inserting familiar stump speech applause lines into debate responses - which only works if done with enthusiasm and clarity (and if received by applause - a big No-No in Lehrer's auditorium, which the audience obeyed seriously and silently). Keenly aware of the grand, grave occasion, McCain wavered between respectful and domineering, and ended up awkward and edgy.
