You never know when the murder-fetishists will have a few lucky days. Sure, they usually wind up killing a lot of people, running the country into the ground, and ending with everyone equally miserable, but they get their bread and circuses first.

Don't worry: the Koch Brothers alone will be spending nearly $1 billion in the upcoming election; I think you can stop clutching your pearls.
