I have a strong feeling that the hybrid-driving set are either delusional or self-satisfied that choosing a "more environmentally friendly" car is a meaningful political choice. John Nichols points out in this article from The Nation that Rudy Giuliani is the only major Presidential candidate who doesn't drive at all. Of course, this only means he takes limos from one thousand-dollar-a-plate dinner to the next. Still, as a non-driving person myself (except in Japan, where I was tricked into a free car for the year), I strongly believe that a totally car-free society is the only kind of society worth living in. I doubt Rudy is that radical, but from a field of hardly differentiated political candidates, I might as well choose one using personal, if only somewhat less arbitrary, criteria.
