so you're saying that the president, who did not live in an area of southern dialect in his formative years, speaking to a crowd that lacks any sort of regional binding to it's description or of it's members, spoke in a southern drawl for a bit in a way to connect with the audience. gee maybe, just maybe there's another group of people apart from southerners who tend to drop their g's (not to mention the waist of their pants!) a group which is far more likely given the situation.
