I question youor definition of ‘best’ and ‘conservative’
You must not listen to Savage very much. Other conservative talk show hosts are sissies compared to Savage in terms of subject matter, range of interesting discourse (from dogs to food and recipes, political analysis, Biblical references, and awesome insight into the soul of people).
Other talk show hosts are somewhat predictable, self-centered, and do not have the intellect and range of general knowledge about history and its relationship to today's events, socio-political context, support for the Catholic Church, support for our military, and ability to convey scientific understanding.
For example other conservative talk show hosts will not or cannot address the vicious unfairness of Savage's ban from Britain.
I must admit that I get bored with Rush sometimes, been listening to him since 1988. There is no contest between the intellects of other conservative talk show hosts and Savage. Savage towers over all of them!
