President Obama trip to New Jersey

Listening in a public speaking situation is important. Listening can teach us how to become better speakers and become knowledgeable in important issues among other things. Please comment in this post after you have returned from your outing at the PNC Arts Center to hear President Obama and Governor Corzine speak. I want to know what techniques did you hear being used by either of these speakers ( or, if another is present) that illustrated a message being adapted specifically to a college audience? What was the message? How was it achieved? Topic? Supporting Details? Delivery? Or something else? Be specific. You need to tie your comments directly information evidenced in the speech. Really listening teaches us many things...and can really open up new perspectives....What did you listen to?
