I'm a long time Dittohead. Rush is superb. Others have followed, some are more conservative, but none are as intelligent and thoughtful and well-spoken.

"...none are as inteligent and thoughtful and well-spoken."
I think Michael Medved qualifies, and probably surpasses, Rush.
There may be others--I don't know all of the different conservative talk show hosts.
