I know there are dumbasses out there. I see them everyday. But look at those people asking McCain these questions. They are perfect stereotypes of your average American redneck. That old lady with her hair, her barely-English hick talk, her clothes? She's was totally set up to ask that question. Notice how she stumbles with her words? She's not an actress, but I'll bet money she was paid to get up and say that stuff.
I underestimate many things: mother nature, bad manners, hangovers --- but I NEVER underestimate Republicans with a marketing degree. Those people are more resourceful than a gold digger chasing a rich old geezer. They'll do anything to reach their goal. Including planting some crackers in an audience to make idiotic statements.
