This is probably a minority view but...I think 'Campaign Trail' is Thompson's best work. Why? Because it a perfect synthesis of satire, unique personal vision and presentation of the forces which shape our political circumstances. And it's f**king funny. Let me enlarge on those main 3 elements though...
Thompson's satire is like Swift's (read the 4th part of Gulliver's Travels and realise that it's more than a children's book if you want to know what I mean), in that its vicious tone is prompted by the author's own dissapointment at the way the more noble tendencies of man are constantly dirtied by human stupidity and greed.
Thompson's writing is probably familiar to most people who will read this review. Rest assured there is more 'Las Vegas' style writing which alone should keep some of you entertained if you don't like the politics.
Thirdly, you probably won't get a better book dealing with the 'noble' art of politics, how it is conducted, and why, despite its ofttimes rotten core, it is still important to have an awareness of the shitpool leaders of the free world have to swim in before being elected. And do you really expect them to smell of roses after this?
Not having had to write for a while has meant that I realise this review could be better. In summing up could I just say that 'Fear and Loathing on the Campaign Trail' is an excellent and funny piece of reportage which deserves a place in the library of those any interest in modern writing.
