Reason for McCain to retire?

(CNN) – Disparagement from members of his own party has Sen. Rand Paul recalling the golden rule: treat others as you would like to be treated.

Responding to Sen. John McCain's condemnation of his thirteen hour filibuster, Paul said Friday that while "I treat Sen. McCain with respect, I don't know if I always get the same in return."

Paul was speaking on The Mike Huckabee radio show. Earlier in the day, McCain told The Huffington Post that Paul, along with Sen. Ted Cruz - who assisted in Wednesday's filibuster - was a "wacko bird" that could taint American's impressions of the GOP.
