You are completely ignorant. Having read three of those books, I can tell you Savage (Weiner then) is a genius. He wrote about supplements that NO one was talking about 30 years ago, and which are huge today, like green tea and CoQ10. One of those books, "Immigrants and Epidemics" predicted that the open border would result in drug-resistant strains of TB in border states -- EXACTLY right. California now spends $2 BILLION on that every year. Savage has TWO PhD's from Berkeley. And that doesn't even cover his historical or political knowledge. Levin is also a brilliant man.
I always liked the fact that Savage can roam into other subjects besides politics.
And in that way he is the opposite of Levin who is very serious 100% of the time.
Having a variety of radio show styles to listen to is valuable because you can get bored with one format all the time.
