Thats the best part about Michael S. is that he only gives numbers when he is talking about factual information, and gives a rant (his opinion) the rest of the time. 
I read all 4 of his political books and he gives a lot of factual information, but really generally gives his opinions.  His latest book the "political zoo" is more of a factual/comical book.
I find his point of view to be inline with mine about 82.7% of the time.
