This comes right out a document from the CIA , on how to use speech when dealing with the public, and how to present subject matter and more so as to present teh infomation in a manner that concludes regardless your point, facts and data used with this in a method that disproves your own evidence or allows it to be INTERUPTED in the manner you want it to be.

IE the spin you hear from Admin. But this is from ALL. I am NOT speaking just about Bush, that WOULD bwe a spin there.
Absolute improvisation does not exist in oratory. All orators have a "mental plan" that allows them to organize their ideas and concepts rapidly; with practice it is possible to come to do this in a few seconds, almost simultaneously with the expression of the word.
The elements that make up a speech are given below, in a structure that we recommend always putting into practice, to those who wish to more and more improve their oratorical abilities:
*Introduction or Preamble: One enters into contact with the public, a personal introduction can be made or one of the movement to which we belong, the reason for our presence, etc. In these first seconds it is important to make an impact, attracting attention and provoking interest among the audience. For that purpose, there are resources such as beginning with a famous phrase or a previously prepared slogan, telling a dramatic or humorous story, etc.
*Purpose or Enunciation: The subject to be dealt with is defined, explained as a whole or by parts.
*Appraisal or Argumentation: Arguments are presented, EXACTLY IN THIS ORDER: First, the negative arguments, or against the thesis that is going to be upheld, and then the positive arguments, or favorable ones to our thesis, immediately adding proof or facts that sustain such arguments.
*Recapitulation or Conclusion: A short summary is made and the conclusions of the speech are spelled out.
*Exhortation: Action by the public is called for, i.e., they are asked in an almost energetic manner to do or not to do something.
