I recall that he was just becoming known in media circles and was invited on Buckley's talk show "Firing Line" and could not take his mind off how Buckley kept saying the Master Shake Down Artist's name.
He does imitate Buckley frequently, not just when say “Reverend Jackson.”
I suppose Buckley must have been an inspiration to Rush.
I do miss William F. Buckley. I am glad he was not privy to his son’s endorsement of, I can not believe this, Obama.
