I'm a bit behind, but I was watching Wednesday's Daily Show and Carol Moseley-Braun was on. John asked her about the proposed Mars trip, and she made the Vulcan peace sign and muttered "Live Long and Prosper", which is weird... but a bit later she then said "Fear is the mind killer" in reference to the whole war on terror and the Bush administration. Its the second line of the Litany against Fear from Dune:

"I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain."

George says she dropped out of the race because she admitted to being a geek. These one two figure that she's a Bene Gesserit. The second one draws further parallels including that Osama bin Laden is the Muad'Dib... hmm.
