Gonzo Suicide

Why do I have this awful feeling that Hunter S. Thompson's suicide has something to do with his inability to stop the Shrub from getting elected?

Myths and legends die hard in America. We love them for the extra dimension they provide, the illusion of near-infinite possibility to erase the narrow confines of most men's reality. Weird heroes and mould-breaking champions exist as living proof to those who need it that the tyranny of the rat race is not yet final. Hunter Thompson, in Pageant (Sept. 1969)
