Taken on it's own, it doesn't appear to be significant. However, in the context of how men are routinely portrayed as goofy, buffoons, and generally unable to take care of themselves on sitcoms and commercials (especially commercials for food and cleaning products), does the harmless appearance change? Yet, in both of these speeches, characteristics of both Obama and Romney were provided with much more detail and context about multiple facets of their personalities. Was this inclusion necessary for some humility in an otherwise overly positive characterization of these two men?
And, would it have been any different if the presidential candidate was female and her male partner was speaking on her behalf?
