Marion Barry, who perspires a lot but wants to avoid giving the impression that he’s jonesing, constantly mops his brow with a starched white handkerchief. Lately we’ve noticed that this affectation has been picked up by his inner circle. At a recent outdoor press conference about the arena deal, for example, six or seven Barry cohorts could be seen blotting their foreheads incessantly, even though the temperature hovered around 40 degrees and there was not a bead of sweat to be found. Is this some kind of fashion statement? Or are Barry’s aides and allies trying to make his flop sweat appear normal, much as in Chevy Chase’s Gerald Ford skits, in which Saturday Night Live cast members playing Ford’s aides would pretend to trip and answer their pipes?
