I'm a big Vonnegut fan, but I don't think political writing is his forte.
I certainly don't think it's his forte, and maybe it was just the state of mind I read it in, but I really appreciated his willingness to spark an issue, but then to leave it, and go with the witt. It leaves the reader to go along their own paths. He's kind of neatly sidestepping political rhetoric.
I realise too after reading this that I must go back and reread the Vonnegut I haven't touched in so long.
