I saw him speak a few months ago. He’s being trained to speak with the same cadence as Obama. It was actually a little creepy. The same pauses and cadence. He doesn’t impress me all that much, but I don’t discount the threat. Obama didn’t impress me, other than his 2004 speech which was actually a well structured speech and well delivered.
There's a school of thought that suggests that Obama's speaking style is a form of NLP (Neuro-Linguistic Programming), which is basically hypnotism. It obviously worked on a lot of people. I find his speaking style highly irritating.
