"There's some extremists there, but the rank and file are just normal people like us."
Yes folks, David Koch is just a normal person, like us. In fact he's exactly like all the other "normal people" with an estimated worth of $21.5 billion, including his brother Charles, for instance, and about four other folks in America. They're a rather 'extremist' version of normal, but hey, who defines 'normal' these days anyway? Apparently the billionaire birthers of the astroturf Tea Party, that's who.
