"Newt Gingrich is not part of the right wing lunatic fringe" (an actual quote)

[gratuitous]

1. The cure for stupidity is education

Once you get your jaw back in place, and if you have an ongoing conversation with this ninny, try to inject a fact or two into the conversation. Or, ask a question that leads the ninny to a fact that contradicts what he says. He may be a lost cause, but he will surely be a lost cause without at least an attempt at education. Maybe, just maybe, a couple of neurons will fire off and his brain will clank into gear.

Good luck.
