For the longest time I disliked Kerry most among the candidates, with Dean second and Clark a distant third. But that’s changing, partly because Kerry’s a much better candidate than he was even a few weeks ago. Increasingly, I find Clark to be the most offensive, albeit in an ill-defined way. He exudes a hunger for power unconstrained by reason. Whether his answers work on paper or not — quite often not — he leaves the impression that he is not only a conspiratorialist but that anything he says can be justified if it gets him closer to power. It’s just a creepy vibe he gives off. All candidates have this to some extent, but most have spent years or decades in electoral politics and so they’ve learned to channel such passions in relatively productive ways. When you watch Clark it all seems so close to the surface.
