Abu Musab al-Zarqawi was the biggest unhinged lunatic on the planet. With his death, Anne Coulter has moved into first place. David Letterman. I'm no fan of Coulter. Letterman is comparing Coulter to a guy that blew up school buses, elementary schools and children's hospitals for the fun of it? I wonder if Letterman would consider Coulter worse than Margaret Ray, the woman that tried to kidnap his son and stole his porsche? Letterman had Margaret Ray killed by a train? That would make Letterman a murderer like Zarqawi.
