compare two different persuasive speeches

This discussion is an opportunity to compare two different persuasive speeches.  Each has its pros and cons.

What was the purpose of each speech (the speech goal)?
What type of organizational pattern did each speaker use? (Review Chapter 13 for Persuasive Speech Organizational Patterns).

Using specific examples from each speech, explain why you chose the organizational pattern.
Was it effective?
Why/why not? (If not, how could it be improved?)

Which one did you like more?  Why? (You are commenting on the organization and delivery of the speeches, NOT the topics of the speeches).
