He speaks in extremes with his analogies, but he is a great man and at least uses sound reasoning to back up his analogies. Granted, most don't hear his reasoning because they stop at the crazy analogy. While I think he limits himself extremely by going overboard with his analogies, I definitely recommend hearing him speak. I remember last year when he spoke in front of a focus group. They had a negative view of him coming in, but the overwhelming majority (both democrats and republicans) came away very impressed.
