hahaha, love you comments. annnnnnd, ever curious, I had to research what a hum bug is. this is what I found from a dictionary online:
1. Something intended to deceive; a hoax or fraud.
2. A person who claims to be other than what he or she is; an impostor.
3. Nonsense; rubbish.
4. Pretense; deception."
yeah, RonLee, I think you got it right as it being a "name" for politicians et al.
