Being a very good speaker, or leader, isn't really about convincing everyone, but convincing a certain group of people consistently. This being HN I don't want to get all that political, but I am sure you can think of a few recent US presidents, from both parties, which were seen as quite charismatic and great at speaking, even though they were seen as unconvincing, and downright loathed by many in their opposition. You can find the same situation in many non-political speakers: The magnetism doesn't really hit everyone. So someone can be very effective and charismatic while turning off a non-trivial percentage of the people: I've seen this in company executives a whole lot. The people that dislike the CEO will bounce quick, and in the end you end up with a workforce that is very loyal, via self-selection. So is he a talented speaker? Just by by how many people react well to him, the answer is yes, regardless of how well he might convince you or me.
