Politics is the dirtiest business there is. There is no contest here. Selling poison to people while branding it as food, like the fast food and beverage industry does, bah! that's nothing. Selling water with lead in it? Easy! Anyone can do that! no problem. War? You think War is dirty? With innocent kids getting blown up by bombs, and mines, and IEDs. Bah! That's easy! Just say: "Collateral Damage". And the problem goes away.

Even Ethnic Cleansing is a cleaner business than Politics. No really! Think about it. When you commit genocide you have a clear, well defined activity. You are exterminating humans that fall in some arbitrary number of categories. And, at the end of it all, you have to do the cleanup yourself. Obviously you do; you just wiped out everyone that isn't you!

See! Clean! A very clean business!
