I know it's something that every prosecutor is taught but, as a forensic consultant, I have yet to see it in practice - even when they believe they're utilizing the principle. K.I.S.S. (Keep It Simple, Stupid). If Kerry can do this in the debate tonight, he's halfway home.
In addition, given the thin skin of the pResident, if Kerry can 'sandwich' many or all of his responses and rebuttals, he'll be all the way home. That is each answer/response should be broken down into 3 segments: 1) a critique of Bush's position, 2) what Kerry would do better and 3) end with the slightest of jabs/teaser to prime the little man's reactionary pump.
