By calling him "self-serving" it tells me you've seen fewer than 10 of his speeches. I've seen more than 100 and he is DEFINITELY not self serving. He serves the people.
Did you actually read the book? I handed out 50+ copies of "The revolution - A Manifesto", and it made a big difference to a lot of people. They kept passing it around. 500 people have probably read those 50 books. It is an easy read.
