FF, particularly for the reason that Oakvale has already mentioned. I also see that Nathan has brought up Hitchens' excellent writing on the Clintons. No one, to my knowledge, has articulated a better critique of the Bill Clinton presidency than Christopher Hitchens has. If Hillary is elected is 2016 it'll be a tragedy that he won't be here to write about it.
Also, I always enjoy going back to his writing and television appearances - e.g. this joint interview on CSPAN, with Andrew Sullivan, is an absolute joy.
Yes, I'm glad Nathan brought that up - I completely overlooked the delightful critiques of the Clintons. There's an excellent documentary about Hitchens from the late 90s which has amazing scenes of him being congratulated by placard-waving proto Tea Partiers.
I highly recommend Ice Spear
