The following are from Ambrose Bierce's "The Devil's Dictionary:"
POLITICS, n. A strife of interests masquerading as a contest of principles. The conduct of public affairs for private advantage.
POLITICIAN, n. An eel in the fundamental mud upon which the superstructure of organized society is reared. When he wriggles he mistakes the agitation of his tail for the trembling of the edifice. As compared with the statesman, he suffers the disadvantage of being alive.
I know, those are pretty dark, but they kind of fit my mood today (not dark, but pretty darn tired of politics).
