It is possible that that Hume was not actually rating Clinton's physical attractiveness and was merely trying very clumsily to say that she did not, in his opinion, radiate the kind of personal warmth that might attract undecided voters — or that the "smug" demeanor he perceived wasn't necessarily a good look for her. (Update: Hume sought to clarify his remark on the air Tuesday: "I was just talking about demeanor. We are not yet living in a society where a female candidates demeanor cannot be criticized. We’re just not there yet, but at the rate we’re going we may get there.")
Clinton probably won't complain publicly about Hume's remark, either, but her backers are already airing a grievance on her behalf.
