Until this morning I’d never thought of Bernie Sanders in terms or images that were even vaguely indicative of any sort physical properties or biological urgency or anything along those lines. For years I’ve only thought of him as a tough, flinty, straight-shootin’ mofo — white-haired, blunt-spoken, Brooklyn-accented, cut the bullshit. Now, suddenly, I’m thinking of some kind of wolf-like predator with certain primal qualities or tendencies that I’d rather not get into if it’s all the same.
