As ABC News' David Wright and Sunlen Miller wrote, Obama seemed to either think Arabic is spoken in Afghanistan or he misunderstands the nature of military translators.Imagine if McCain -- or any Republican -- had made such an error. Most Republicans would be characterized as ignorant chicken-hawks. In McCain's case, of course, it would be suggested that he's knee-deep into senility because of his age.Well, maybe Barack's gaffe-proneness is attributable to his age, too . . . as well as to a heaping helping of inexperience.
