My suggestion (inspired by a conversation with Deborah Katz Hunt) is that the Libertarian party run magicians Teller and Penn (both libertarians) as its presidential and vice presidential candidates. The campaign commercials would show a stone-silent Teller standing next to the talkative Penn. Penn would say something like"our candidate, Mr. Teller, wants you to know...." You get the picture.
If the Liberatarians did this, they would expose more Americans to their ideas but they would blow the geriatic/stodgy Nader out of the water. The ball is now in the LP's court!
