Dean's bizarre behavior in "imitating" Mr. Limbaugh's (non-existent) cocaine addiction, even if it were true, violates medical ethics in the extreme. He is a massive embarassment to the medical profession, as well as demonstrating an absence of basic human decency. Thank goodness that the other MD in national political life, Dr. Bill Frist, shows an unceasing high degree of class, morality and ethical behavior.
