Watching or reading about him is pretty much the equivalent of (sorry to be so graphic, but there’s really no better example) popping an enormous pimple on your chin. You know no good can come of it. You know, in fact, you’re only making things worse by encouraging the growth of more pimples, not to mention inviting a festering scab that will turn into an unfortunate scar. But it’s just too satisfying to turn away from.
